Well....  I "cloned" my head slice (4) to slice 3, updating source on
slice 3 to r313995, rebooted to slice 3... and noticed that it didn't
seem slugglish at all (unlike the earlier "smoke-test").

So before I did anything else, I rebooted it... and the countdown after
"Syncing disks, vnodes remaining..." was about 1 second each.....

So I'm not sure what happened, but it looks as if I can't (readily)
reproduce the symptom.  I'll try experimenting a bit more as time
permits today (but I actually use the laptop in my day-to-day work, so
that may prove challenging).

Sorry for the noise.

How could one possibly "respect" a misogynist, racist, bullying con-man??!?
