Hello,

Sometimes pthread_mutex_lock ou pthread_mutex_unlock block.

In order to reproduce the problem, I have made a test application
(test.c) who always block

$ gcc test.c -o test
$ ./test
thread id=1
after pthread_create 1
after pthread_create 2
thread id=2
thread id=3
after pthread_create 3
after pthread_create 4
thread id=4
thread id=5
after pthread_create 5
thread id=6
after pthread_create 6
after pthread_create 7

The application can create 1,2,3 threads or many more before blocking.
