Summary: os.wait child process fail when under stress

Initial Comment:
when having high amount of threads forking, os.wait fails from time to time giving a "No child" error". If you retry, eventually it will work.

Note that on some versions of Linux 2.4, calling wait() can return ECHILD
even when there is a child.

What operating system are you using? 

Why do you think this is a bug in Python and not in your operating
system?

Are you sure there are any unwaited-for children when ECHILD is returned?
