I need to invoke an external program (gcore), which takes PID as
argument. On Windows I do something platform-specific, but that
also requires access to PID.

I'm currently rewriting this patch to also remove the duplication
between ExecuteAndWait and ExecuteNoWait.

A one-line GetPid() method is not so dangerous IMO.
