Hrm. I know about the memory/cache issues, but it sounds
like there's more on the CPU side I don't know much about.
Is there more here beyond the memory question and
prediction/pipelining?

I'm reading the PDF you referenced now.

// Speaking of which -- is SPARC port of Plan9 still alive?

Not really. There's a partially-working sparc64 port out there
which ran on the Ultra 1 (I think), but it's neither been kept up
to date nor made to run on anything beyond that. A few folks
(including myself) have poked at it a bit with varying results,
none of which were particularly good.

Something on Batoka would provide better motivation than my
old Ultra 5, though!
