it was locked.
All of libpthread tests are successful with pthread mutex

I'll polish the quick hacks for libpthread and send it to the list.
Also, did you try some more complex programs?
Not yet. I'm looking for a
So I was reading about system calls this week and I noticed that generally
we write wrappers which handle the syscalls from programs. So if a system
call is encountered, it calls this wrapper which then makes calls to the
kernel to perform the task.
So I presume that this wrapper is glibc in
