The theory is, I guess, that Suns are either single-user machines, or
servers that shouldn't have lots of people logged in to them.  "maxuprc"
is set to MAXUPRC, which is set to NPROC - 5 (NPROC is 10 +
16*MAXUSERS).

The theory doesn't always correspond to reality....

It's been that way since before 4.0....
