I tried this solution a while back and found that if the progress bar was
updated at all frequently, the overhead involved in dispatching and
processing AppleEvents slowed down the whole task considerably. I can't
remember if I was sending AppleEvents or issuing AppleScript commands
(sending events directly should be quicker) but either way, I found it too
slow.

I tried some experiments with publicly-available XFCN's, but that didn't
work either (probably because the typical XFCN needs a window context that
it gets from HyperCard, but which MacPerl can't provide).

Matthias's new GUI components might offer a better solution. If I get a
moment, I might look into that, since I'd very much like to have a progress
reporter of some kind.
