Sure, that's why the Process.wait call hangs the program until you 
interrupt it.

The thread owns the process in one sense: the thread continues (and in 
this case finishes) when the process exits. I'm just wondering whether 
it would make sense for the thread to be more closely associated with 
the process. Maybe killing the thread should not kill the process, but 
instead there should be an additional status result that tells you 
whether the thread is sleeping waiting for an external process and if so 
the command line and the pid.
