I have applied the patch (and recompiled) and am letting the system run
full steam right now (including the milter, etc); the initial results
look promising as it has not exhibited the aberrant behavior as of yet.
I will post a followup after letting this run all night (assuming it
does so) or after it fails (which hopefully won't happen).
