Perhaps. That depend on the bottleneck. If there are CPU or IO
bottlenecks, parallel booting will not speed up the process much. :)
I'll need to measure to find out. :)

Not sure. I consider adding it to the pkg-sysvinit svn if the license
is GPL (the same as sysvinit), to make the code more accessible, but I
am not sure if I want to use your program or the startpar code to
start scripts in parallel. :)
Your rc program is equivalent to the current init.d/rc script when
CONCURRENCY=shell, but I want to find a good way to serialize the
output from the script before recommending to use either of them.
