ClockServer sections can now be specified in zope.conf. If you specify 
them with a period of say 10 mins (or even 2) then the queue should 
never get too large, and the linear search time is not a problem as n is 
small.

Essentially you end up with a solution very similar to QueueCatalog but 
with the queue being searchable.

The pain is then in modifying all of the indexes to search the queue in 
addition to their standard data structures.
