+fbtl - based on nptl
+
+
+original dir is pruned snapshot
+of nptl (and nptl_db) in HEAD as of 20130621
+
+Goal is to put needed bits into fbtl subdirs of kfreebsd
+and modify what is needed in fbtl. We will see later how to proceed further.
+
+The freebsd kernel provides basic futes-wake and futex-wait operations.
+By default they operate on long, but later API for int have been provided too.
+There is no FUTEX_CMP_REQUEUE, the condition have to be implemented differently.
+
+The kernel lwpid is in range which fits into int, but the storage is long.
+
+1st pass would be to provide the same set as linuxthreads - i.e. nothing shared

+Now that the Linux kernel is once again able to run all the tests we
+have and since glibc 2.3 was released it was time for a new code drop.
+I've uploaded the second code drop for the Native POSIX Thread
+Library:
+
+ ftp://people.redhat.com/drepper/nptl/nptl-0.2.tar.bz2
+
+You need
+
+- the latest of Linus' kernel from BitKeeper (or 2.5.41 when it
+ is released);
+
+- glibc 2.3
+
+- the very latest in tools such as
+
+ + gcc either from the current development branch or the gcc 3.2
+ from Red Hat Linux 8;
+
+ + binutils preferrably from CVS, from H.J. Lu's latest release for
+ Linux, or from RHL 8.
+
+
+Compiling glibc should proceed smoothly. But there are a number of
+tests which fail, mostly because some functionality is missing in
+glibc. Ignore those errors. It is only important that all tests in
+nptl/ are passing. Run
+
+ make subdirs=nptl check
+
+to run all thread tests.
+
+
+This version features several improvements:
+
+- all APIs are now implemented;
+
+- fork handling has been improved; stacks in the child are freed;
+ atfork handlers are removed if they were registered from a module
+ which gets unloaded.
+
+- pthread_tryjoin_np and pthread_timedjoin_np are implemented
+
+- TSD handling corrected and optimized.
+
+- many more tests which also test the underlying kernel implementation.
+
+- the build infrastructure has been implemented so that the DSO and
+ archives are built in usable form and with correct named.
+
+- libthread_db has been implemented. This is the library which is
+ needed by all program which need to get access to internals of
+ libpthread (mainly debuggers).
+
+- the CPU clock functions are implemented
+
+
+
+The white paper hasn't yet been updated. It's still available at
+
+ http://people.redhat.com/drepper/nptl-design.pdf
+
+
+This release should be ready for some serious testing. I know it is
+hard to compile which I why I'm looking into providing binary RPMs.
+They can be used on non-critical systems. I'll only be able to
+provide binaries for RHL8 based systems, though, and the kernel still
+must be installed separately.
+
+
+The next steps will include:
+
+- write more tests and fix the bugs which are discovered this way
+
+- update the white paper
+
+- write and run more performance tests
+
+- port to IA-64
+
+
+Interested parties are once again invited to join the mailing we
+created:

+
+lll_lock_wait - probe in low-level (assembly language) locking code, only fired
+ when futex/FUTEX_WAIT is called (i.e. when trying to acquire a
+ contented lock)
+ arg1 = pointer to futex
+ arg2 = flags passed to the futex system call

+- we should probably extend pthread_mutexattr_t with a field to create a
+ single linked list of all instances. This requires changing the
+ pthread_mutexattr_* functions.
+
+
+- a new attribute for mutexes: number of times we spin before calling
+sys_futex
+
+- for adaptive mutexes: when releasing, determine whether somebody spins.
+If yes, for a short time release lock. If someone else locks no wakeup
+syscall needed.
+
+
+
+- test with threaded process terminating and semadj (?) being applied
+ only after all threads are gone
+
+
+
+- semaphore changes:
+
+ - sem_post should only wake one thread and only when the state of
+ the semaphore changed from 0 to 1
+
+ this also requires that sem_wait and sem_timedwait don't drop the
+ post if they get canceled.
+
+ - possibly add counter field. This requires reviving the
+ differences between old and new semaphose funtions. The old ones
+ stay as they are now. The new once can use an additional field
+ wich is the counter for the number of waiters
