When a paging system fires up a bunch of processes, a "few" pages of 
each process is stored on the swap device to allow the system to grab
the next block of memory from contiguous disk instead of of a fragmented
one. When you are logged off there are several processes still running
namely getty, init, cron, vhandler, etc. This is normal. If memory is
a problem BUY MORE memory! A rule of thumb for the 386 machines running
a UNIX (not Xenix) kernel is 4 megs for o/s and 1 meg for every Simultask
user. If all of your apps are *nix, then take your best guess, you are
safe with 1 meg per user.
