Thanks!

Note that you've found references to 'ipc_pid_t'. I've already included
support for 32-bit pid_t in my patches to the IPC code, needed to support
32-bit UIDs there.

Now, actually supporting 32-bit (or 31-bit :) pids will require other
changes, and will possibly break many non-glibc programs...
