Actually I think I did it today. The biggest problem with v1.0
implementation was that expunges could be counted multiple times if
multiple processes were running.

I ran imaptest for a while with 10 connections and in 3 different tests
the dict quota always contained correct values, so I thought it was
probably working.

Even if filenames had the ,S=size? Another problem is that the quota is
read, and possibly recalculated, much more often than is really
necessary.. I haven't fixed that yet in v1.1.
