I'm not sure I understand what you mean.

As far as I digged into Howl, you will have to call their runloop, which
will never return (!) and use some delegate functions that handle
"messages" from the runloop (kinda similar to Apple's implementation).
You can probably "isolate" the runloop in a separate thread (well,
that's what the docu suggests) but, as I said, AppKit isn't thread-safe,
so you might run into several problems here.

Probably, if you're willing to spend the time to figure out how the
stuff in Howl actually works. I just noticed from reading the docu, that
some parts are (or at least seem to be) missing.
