You are not using the pi.hProcess anymore, so you must close it.
No. If I do, the pid becomes invalid after the process is finished,
and waitpid won't work. I couldn't find anywhere were we actually were
closing the handle, even after it was finished. So I don't think we
leak any more than we already did (for non-daemon purposes).
Previously, this handle was closed by _cwait() (it was the "pid"), so we 
didn't leak it.

I somehow thought that you need the process ID instead of the handle for 
TerminateProcess, but now I see that this is not the case (it takes the 
handle). So I don't see the point of this change anymore. You say the process 
handle "does not work consistently with getpid", but I don't know what you 
mean. Please explain.
