Howdy!

It's been a little while since I used POSIX threads, but are you waiting
for the threads to finish once you have created them? I can't quite
remember if this is the way it werks, but if the main() function ends
without issuing a pthread_join() call, the whole process will end
including all threads.  But since you are detaching the threads this won't
work. Something to think about tho. 

Try exiting normally from the start function of the thread (with a return
call) rather than an explicit pthread_exit perhaps.

Don't worry over what other people are thinking about you.  They're too
busy worrying over what you are thinking about them.
