Oh, interesting. Note that we already allocate from the pid space for
other things, so it's entirely doable. Another choice would be to simply
disallow the thread group leader from exec'ing. Linux threads traditionally
try to remain as close to process behaviour as possible, and allowing an
individual thread to exec is very useful, so I'm still in favour of
allocating a new tgid.
