[plt-dev] latest version under Windows

I've been noticing occasional hiccups where either GC pauses seem 
surprisingly large or -- what happened to me just now -- DrScheme just 
becomes unresponsive and I have to kill it. Sorry I forgot to check if 
the CPU usage was pegged before I killed it. I will try to pay more 
attention next time.

Anything more specific I should be looking for?
