[SunRescue] best OS for a SMP SS10

[Dave McGuire]

  Jeeze...don't flame me for this, but from personal experience, SunOS4
will *scream* on that machine.  I realize the SMP support isn't
optimal (no fine-grained locking) but it will be very, very zippy and
one can compile pretty much anything under that OS.

  I'm not really *recommending* it, but when the alternatives are things
like 1) slowing the otherwise reasonably fast machine down with
Solaris and 2) losing the second processor with something fast like
NetBSD/OpenBSD...depending on the application, I'd have to consider it.
