[plt-scheme] Slow DrS on slow net

Hi all,

I've noticed that on the machines at my school, DrScheme often takes  
very long (as long as 30-40 sec) to return control to the user after  
"Run" is clicked or an expression is entered in Interactions), and the  
problem seems worse for larger programs or programs containing image  
snips.

By default my school's machines (all running Vista, btw) save files to  
a network drive, and my school's network is pretty slow.  Saving files  
to the C: drive eliminates this problem.

So I'm wondering, what is DrScheme having to go to the disk/network  
for, and are there any options we can set (in prefs, environment vars,  
etc) to prevent the costly network accesses? (longer term, I'll be  
talking with our net admin about ways to improve the situation...)

Best,
Jordan
