Comment (by jackburton):
In theory "waitpid(-1, &status, WNOHANG)" should tell if a child process
has exited or not, and thus be used to tell if a program is still running.
In practice, I've experimented with it a bit, but there seems to be no
difference in the returned values.
Maybe since "bash" is already a child process, waitpid() will always
return that there are still child processes runing.
