Hello,

Sometimes pthread_create block and never return.

I have made a simple program (test.c) to reproduce the problem.

> gcc test.c -lpthread -o test
> ./test
thread id=1
thread id=2
thread id=3
thread id=4
........
thread id=3736


Sometimes pthread_create block after creating arround 10 threads,
sometimes after creating arround 10000 threads or more.

The test program work well under linux.
