mfind --parallel does nothing (is never used)

[arekinath]

mfind currently does parallel operations (using a vasync.barrier), but never uses the value of the -p/--parallel switch to limit their concurrency.

[bahamas10]

-p/--parallel is currently being used by client.ftw which mfind makes heavy use of. I verified this by manually printing out the value set before the queue was created.
