Yeah, pretty much what I was thinking. I'm still undecided how 
LinuxHost.java should message back that the corefile executable has not 
been found. I could raise a (checked) exception, but that somewhat 
indicates an error condition when it is not. I could implement 
callbacks, but that would require a declared interface, which may muddle 
the very simple and clean interaction now.

Any ideas?
