Okay, that's what I (eventually) figured out.  Does it present a
problem for my plugin to have its own main loop (as in the email I
sent a few minutes before yours)?

I *think* that's what I'm doing by starting the main loop after
spawning the process, and then stopping it when the process completes.
 So far, I haven't run into any problems.

I discovered the problem of query models + multiple threads... not
good!  I was thinking of the gtk.TreeIter idea - having some kind of
signal-callback system where it progresses to the next item, but it
seems like a pain.

um... thanks?  ;-)  I really appreciate the help, I'm mostly shooting
in the dark here.
