because PAGs should be associated with process groups, not just per user.
you might want to use different permissions (such as admin) while also
using your ordinary user permissions elsewhere on the same machine.

that being said, i think it would be enough to produce a mapping between
PAGs and the process group leader's pid, uid, and start_time.  start_time
wouldnt be necessary if you could track when a process group ended but
alas that is not possible.
