Abstract: There are times when resources other than the usual I/O
devices must be shared.  These may include code segments,
data structures, directly accessed devices, etc.  In order
to manage these resources a special driver is used to
control access based on task priority and queue position.
The driver may control a virtually unlimited number of
resources.  Two versions are provided, a vanilla version and
one that checks to see if the requesting task is privileged.
Use of a driver instead of other methods avoids resource
lock up due to tasks shorting.  This approach may also be of
interest to VAX users.
