Does anyone allow unlimited or extremely large quotas?

Ok - that's definitely fixed in 2.4.  I'm also attaching some patches
against 2.4 if anyone else wants to have a play with them.  The first
makes Cyrus open the index and cache files O_RDONLY if the index is
locked in shared mode (which implies a read-only session).

The second patch then makes index EXAMINE commands use a shared lock!
