So far, nothing inside of TORQUE sets offline, it is always done by a
sysadmin (or a script written by a sysadmin). Me resisting that change
is one reason.
The other reason is problems with clearing the offline bit. If we had
pbs_server set offline, it couldn't clear it again because we'd have no
way to distinguish between a server-set offline, or a sysadmin-set
offline. It would be one-way.
The one-way setting is also complicated by possible transient errors.
large numbers could be set offline for some silly transient thing and
require lots of cleanup from the sysadmin.
With these issues, a cronjob is nice an easy :)
