While in theory the pid that is used for tgid should never die while the
thread group exists, this case needs to be handled for thread groups in
general. The number shouldn't be re-used for a pid as long as it's in use
as a tgid.

Are there any programs that use CLONE_VM and not CLONE_THREAD?
Actually I think we should make tgid visible in /proc in general because
it's a useful thing to know, whether it's the right mechanism for gtop or
not. I'll work up a patch.
