Out of curiosity, I gave maya.utils.processIdleEvents() and mc.refresh() a
shot, and those both seemed to do the trick. Though I was testing in gui
mode, and sometimes those don't work so hot in batch mode... so you might
want to test that if you need it there.

According to the docstring for executeInMainThreadWithResult, if you're
already in the main thread, this essentially doesn't do anything... were you
thinking of maya.utils.executeDeferred? Of course, then you'd have to find
some way to get the result back...
