nice! I hope Helmer can take a look at the patch, since he's been 
working on the same problem.

I like the way Mark's changes introduce Classpath's separation of 
VM-dependant implementation bits in VMSomething classes. That will make 
further merges of the code with Classpath easier.

Adding copyright information to a file is fine. When I want to know who 
wrote what, I usually use CVS and the ChangeLog, though I guess 
explicitely saying that developer X has worked on some file Y doesn't 
hurt. ;)
