On i386 libthr limits an application to 128 _concurrent_ threads. So, you
should check the return value from pthread_create() for EAGAIN, in which case
you should retry again.

Great! I've been waiting for this message to appear for some time. Do you have a
backtrace by any chance? If not, that's Ok, even without it the program is
simple enough that I know where to start looking.
