I noticed that quotas were wrong if our cluster was shut down several times in
one week.  (We ANALYZE/DISK once a week.)  I found out recently that our disks
were not always being properly dismounted at shutdown, the apparent reason
being that some spooled printers had a channel open on a disk.  I added code to
SYSHUTDWN to do a SET DEVICE/NOSPOOLED, and we're monitoring disk quotas to see
if there is any improvement.

Sometimes, one or more of the SET DEVICE/NOSPOOLED commands fail with the
messages:
          %SET-E-NOTSET, error modifying TXC2:
          -SYSTEM-W-DEVASSIGN, device has channels assigned
This error occurs after SHUTDOWN.COM issues the STOP/QUEUE/MANAGER command,
which should have stopped all the symbionts.  It may be happening only for
printers which have a current job when the system is shut down.  Does
STOP/QUEUE/MANAGER complete asynchronously, i.e. should I put a WAIT statement
in before despooling the printers?  Or, does it wait for the current job to
complete?
