+1.  The utilization of the underlying storage and the value calculated
by Cyrus may not correspond 1:1 for a variety of reasons [although, I
guess one might expect them to the close-ish - unless delayed expunge,
deduplication, etc... features are used].  I have seen the filesystem
and Cyrus quota values differ into both directions [f>q & f<q] for
apparently valid reasons.
