Traditionally PIDs fit in 16 bits, let alone 32.  I'd recommend that we
standardize on casting pid_t to int for printing purposes; I think
that's what's being done in more places than not.  Also, as you note, we
are using int variables to hold PIDs in many places --- I don't think
it's worth running around and changing those either.
