Are you sure that every place you touched gets a system PID, not a
thread ID?  They used to be ints, but were changed to unsigned long
because NPTL's TIDs do not fit in an int.

Also, do Windows PIDs fit in an int?  Win32 pids must, but I expect
we'll get a Win64 port at some point.

I'd like to know the advantage before moving all the deck chairs round
again.
