Furthermore we should investigate the pmap specific cleanup for all archs.
The alpha had an explicit assertion that the pmap cleanup would be done on an
active pmap (if I remember what Nathan said correctly), which is not true
after this change, so the alpha pmap needs fixing. Sparc64 suffers from
random corruption of a free list used in pmap cleanup after this change went
in (details not yet analyzed).

Maybe others have problems too - we should check that now.
