Let me say that this solution, and any other which loops through all

Bill,
We will only have to go through the while loop in rare cases where main
thread has done pthread_exit() before other threads (and hence it's task->fs
is null). Also, even in most such cases, the very first iteration through
the while loop will get us the 'fs' pointer, so we won't have to loop
through all threads. So I think this won't have scalability problem. Am I right?
Thanks,
Sripathi.
