Yes. If the general opinion is that Classpath's VMProcess is better than 
ours, then I am in favour of switching to/merging with the classpath 
version. However, the native part will need to be converted from JNI to 
CNI, because to use JNI we'd have to have a separate shared libary for 
it. Translating the native code should be relatively straight forward 
(CNI is easy) and I'm happy to help out here if needed.

Not AFAIK.

Yes. Ideally it would be nice to leave win32 in a working state if we 
can do so cleanly, but if breaking win32 temporarily is the price of 
getting a better Process implementation, then that's ok.
