A follow-up to my own question.  Might this load be due to come contention
of these ~600 smbd processes onto the various ".tdb" files (and that
general mechanism) introduced at 2.2.0?

This is pure speculation at present, of course.  Anyone got any hints on
how to begin to monitor this (even if only to disprove the idea)? 

(Although I have, sadly, retreated to 2.0.7 on the main fileserver, we
still have three smaller, but significant fileservers (40-80 smbd
processes each) on the new 2.2.0 version.)
