Yes, it could effect linuxthreads.
I think it will be fairly easy to fix - I just have to add a check
after it gets past the blocking condition to see if it needs to reload
the alternative page table.

I found the KSE bug that was stumping us last night. Julian will be
a happy camper when he wakes up! I found a bunch of minor issues as
well, things like buildworld erroring out in libkvm due to the structural
changes, but I expect he will be able to commit the KSE patchset very
soon now that we've found the bug that was making such a huge mess
of the machine.
It turns out that some assembly in swtch.s got munged and pmap->pm_active
was not getting set, having the side effect of causing most of the TLB
invalidation routines to believe that they didn't have to do anything.
You can imagine the result!
