Now running a new /unix.  The magtape driver's error handling has been
improved in some small ways, including a reduced number of retries (going
past a couple of retries is the kiss of death anyway).  More important, the
Unibus-map allocation code has been totally rewritten to permit multiple
simultaneous allocations.  This is the major kernel mod needed to get disk
and tape running simultaneously during backups, for an expected factor of 2
performance improvement.
