 A quick update, which of course occurred to me after I sent in the 
 details of the workaround and blamed it on the pmap(9) code.  I wonder 
 if the actual bug isn't that the 'pmap_previous_active_lwp' isn't being 
 set to NULL when lwp's are exiting, and thus the short-circuit fires due 
 to incorrect state being passed to pmap_activate() rather than an actual 
 pmap bug.
