Linux already has enough latencies, even in 2.4. More are not needed.
Ingo Molnar (and possibly others) has been doing work on this, but I
can't get a kernel built with his patch applied to work. Shame.

Certainly. No operating system kernel is going to be appropriate for
all situations. A nice microkernel fits the bill there.
However, I'm talking about super-servers derived from pre-existing
operating systems, which will be roughly the same size as the
equivalent kernel. Running Linux or BSD on a microkernel buys you

I shine my torch around, and I see big signs saying ``Paul's Ignorance
Starts Beyond This Line''. Embedded and distributed system are
another thing I'm not qualified to have an opinion about.
