Another 'fix': added a timeout before vm.resume()

I think we have a race condition: vm.resume() is called *before* the VM is
actually ready to resume.  That is strange, since the debugger is
attached, eventQueues are set up and ready...  Still, waiting for a bit
ensures that the VM actually resumes.  This behavior was not present when
Java 1.6 was still used.  Is this a bug in Java 1.7? Or is it simply that
the VM in 1.6 started up quickly enough to hide the race condition?

I'll continue looking...
