LOL.  Immediately upon sending that msg, there was a power outage here,
which left behind corrupted files in at least 3 (non-ZODB) applications I
had running at the time.  One of them offered to recover from its last
auto-backup, and the other two went insane.  It would certainly be nice if
persistent ZEO cache files got out of the "went insane" category :-(.
