The 'strace -f' doesn't work nicely with LinuxThreads.

I have not analyzed this in detail, but I believe this is because
strace does 'waitpid()' in a loop, and sometimes collects clone()d
processes that the thread_manager thread itself is expecting
to collect.

However, this shouldn't be the case for NPTL (you have been tracing
with NPTL, right?)

I have everything :)
Well, I have FC2 and FC4 readily available (booted up).
