My interpretation of the instructor's comment as originally posted was
that with the "migrate stgpool" command a single thread managed all of
the migration processes, while in a threshold-initiated migration each
process was managed by a separate thread.

That was my read of it, anyway.  And the apparent behavior seems to
suggest the instructor was incorrect, and that both methods of starting
migration do in fact result in one thread for each process.
