There are a couple of uses of the global scheduler lock in some
architecture specific locations. They will continue to be safe with the
4BSD scheduler. I intended to work on these issues with the architecture
maintainers after the threadlock patch goes in. Can you suggest some
alternative to sched_lock for pmap_switch in ia64?
There are a couple of these small issues that should be perfectly safe
that I was hoping to address outside of this patch so that it didn't get
too big.
