My take on this -

#1 sounds right, but the delay to restart has to be pretty reasonable.
(Wacky idea: If startup really does take a long time and that can't be
fixed, how about starting a "hot-spare" VM in the background and
swapping to it when the user resets the interactions window?)

#2 depends on how it's done.  We don't want the students to react to the
display of the root directory by saying "oh! So that's where the
computer wants me to put the file!".

My off-the-cuff opinions:

1. Executing "java <classname>" in the interactions pane should reset=20
the interactions pane.
2. Perhaps the root for file path names in the interactions pane should=20
be displayed when a file
   is not found so that students know why their command failed.

That's a really interesting thought...  I don't think it should be the 
default, because having 3 JVMs running with less than about 256 MB of 
memory will likely kill performance, but for people with plenty of RAM 
to spare, that could be a nice speedup.

Not exactly high priority, but it could be a cool side project.  I 
wonder how messy the synchronization issues would be.
