Bug#842796: libc recently more aggressive about pthread locks in stable ?

I believe that similar bugs have been afflicting hurd and kfreebsd debian ports
for some time.  In retrospect, it's too bad these reports weren't given more
attention, because it could have made things better for Linux platforms as well.
