Maybe someone out there has a solution to a problem...  I'm
looking for a computer system that can handle very large
numbers of executing processes .. none of which use that much
cpu time individually.

The system must run unix - BSD based ideally (or must have
BSD compatible networking).

Overall spead isn't all that crucial, a couple of vax mips would
probably be sufficient, but I'm looking to be running (constantly
when it matters) at a bsd style load average of over 50, perhaps
100.  While I'm doing that I don't want all of the available
processor and memory bandwidth used for the context switches.

I also don't want anything too expensive .. something that is
able to run 100 simultaneous processes well by supplying 25
processors, so each has to cope with only 4 context switches
a second is almost certainly going to be too expensive.

Finally, it must be something available now, not coming sometime
in the future.

Any sugegstions?
