Linux glibc2 pthread_create() returns ENOMEM (12) when one exceed process limits. (It looks like it should return EAGAIN, but that's another story.) For reference, see: http://www.opengroup.org/onlinepubs/7908799/xsh/pthread_create.html """ [I have a feeling that similar bugs were fixed before; perhaps someone could check that all error checks no check for != 0?]
