It cannot.  isRunning checks a local boolean, it does not do any OS  
queries.

Now, once you have a reference to a running process, I'd say it's probably  
possible to add isRunning methods that call on the OS functions.  Given a  
process ID, getting information about the process is pretty  
straightforward.  I think this might be a good addition to std.process if  
it's not already in there.

It's just the getting of the pid based on the name is not straightforward.
