Thanks for the bug report. There seems to be some problem with
reactivate not killing processes. It also seems to be particularly
left-around lpr processes causing the problem for people.
You also described problems printing from acroread. It's not clear to
me whether those problems only happen when the workstation is in the
hosed state (with the extra lpr processes) or if it happens on a
correctly-functioning workstation. Can you clarify?

That's no bug; lpr is setuid root.

That's not uncommon for processes which have lost their terminal or
such in an unexpected fashion.
