-        - use mailbox_close(). check that no transactions are open. maybe

+    - purging seems to be inefficient. run imaptest for a while, get >500
+      files, start purging, it's slow until there are about 100 files left,
+      then the rest is suddenly fast.
+    - make sure that when reading mdbox mails sequentially the data is being
+      read from disk in n kB blocks and reads cross mail boundaries and when
+      reading the next mail it uses the previously read data in buffer

       consistency

-    - dbox: we get back to dbox_sync_file() over and over again when expunging..

     - figure out a way to efficiently trigger purging when user has too much
