Sun 4 \"KNEE\" Wars

[weiser.pa at xerox.com]

aglew at urbsdc.urbana.gould.com says:
"I don't have Sun 4 source at hand right now, but if their scheduler
is similar to the standard BSD scheduler a process coming out of
a sleep may [*] have its priority boosted. ...[further explanation here...]"

But this explanation doesn't explain why Sun's show this behavior and Vaxes
don't, nor why Sun-3's, with 8 MMU contexts, show the knee at 8 fast sleepers,
and Sun-4 with 16 MMU contexts show it at 16!
