+Here is a small patchset adding support for database compaction when supported\r
+by Xapian. Here I add a function which both compacts and closes the database.\r
+This is due to it being not entirely clear whether one is allowed to compact\r
+the database while it is being held open for read/write.\r
+\r
+\r
+Since it is nice to be able to hold the read/write lock while compacting, I\r
+close the database only after the compaction has finished which Xapian seems to\r
+be fine with. That being said, the database is moved after compaction, so it seems appropriate to lump compaction in with closing the database.\r
+\r
+Lastly, I wasn't entirely sure whether/how Xapian's status messages should be\r
+presented to the user. At the moment I simply spit them out on stderr. Perhaps\r
+I should just pass a callback to notmuch_database_close_compact and leave this\r
+to the caller?\r
+\r
+Cheers,\r
