For the record, I've never seen the Solbourne code but I wanted to. Seemed
like they were Unix people. They took SunOS to a better place. I suspect
Greg Limes would agree.

Which is part of the reason we liked it. I loved
SunOS 4.x but it was
also a uniprocessor kernel (Greg Limes tried to make it SMP but it was not
a kernel that wanted to be SMP). I loved it because I could understand
it and it was a bit more complex than v7.
David Barak and the OS group as Solbourne wwere able to do it for OS/MP.
First as a ASMP kernel where CPU0 ran the unix kernel, but scheduled jobs
for all the other CPUs, the as SMP where the kernel could run on any CPU
with progressively finer locking on each release.
