"cpu_switchto() doesn't switch address spaces.". I know sparc currently
needs to play with address space identifiers on switch. Could lazy switching
be done for that instead?
I noticed that you implemented monitor/mwait, which was on my list of SMP
tasks (thanks!). It might be useful have a "bool immediate" argument. If a
high priority LWP has been released (e.g. realtime) it would probably make
sense to force the resched to happen immediately.
