Yes Timo, initial use after enabling this seems to have helped dramatically.
The wait time on my 13k+ folder seems to have dropped from about 10 seconds to
less than 1 second.  Thank you for the suggestion.

What, if anything, am I sacrificing, or what new problems might I cause, by
using mbox_very_dirty_syncs=yes?    Previously I was using mbox_dirty_syncs = yes.
