Pushed a few lines of code in the 'upgrade_index' function. Though it 
still lacks the annotation storage usage computing.
It's in the branch 'gnb/annotate/fixes'; commit 
ed61f721487804b205e399c538fc35ddc153bd93.

Nice idea :)
Pushed a few things.
Added an option hash so that when running commands:
   - test can run system commands (based on the current code which would 
run cyrus commands inside the current cassandane instance directory)
   - finer I/O redirections are possible
   - working directory can be specified
While adding those new 'features', I still kept the 'run_utility' method 
(cyrus commands) and simply added the 'run_command' method for other 
commands.

Then, as you suggested on IRC, I added an 'unpack' method to extract 
tar/gz/bz2 (and combinations) files using system commands.

And I added back my quota upgrade test from a cyrus v2.4(.11) mailbox, 
using two tar.gz files containing a mailbox content and its quota file.

It's in the 'quotamessage/gnb/annotate' branch; commits 
d2bf4e4f42f7f8c9b53713441116ddbea5b0a265, 
86a52daeed5a03f078b88de67d3d10b51a7f8cc4 and 
fb827e8fc77529a5e23465d2c19d6e88adf7cae8.


Maybe you won't keep everything I pushed, but I hope some parts will be 
helpful :)
