If one does a 'man ps' there is a flag called SULOCK which says that the
process is locked in core: 

 SULOCK      0000040 user settable lock in core

There is documentation floating around on how to do this on a Sun 386i by
'writing your own syscall', but I was wondering if it is possible to do on
a Motorola Sun 3/60, 3/260, etc.  I would like to do this to prevent a
process that is only used infrequently from being swapped out (some
almost-real-time unix).  Has anyone does this?
