What about printing a decent error message if it does happen? (for 
example, someone stomps over the pool object, causing a call to 
pthread_join with garbage thread id)

I can see the pthreadpool code currently does not include debug.h, maybe 
for dependency reasons, but IMHO you want an error message printed when 
a system call fails unexpectedly.

Thanks,
Uri
