[plt-scheme] DrScheme hanging occasionally

Hmm... I'm using 208p1.

I do of course, get the GC stall, but that's always less than a second
or so in my experience (I'm not working with anything I'd call "big"
data or source, and this is on a pretty fast machine).

The hang I was referring to don't have any animation of any sort going
on, and Windows says that the process isn't responding (i.e. it's not
processing Windows messages). I've left it for up to a few minutes,
but I would say it wasn't coming back. When you say "stall" do you
mean it never comes back, or just pauses for a while, but comes back
