The timeout is 500ms by default (at least on trunk at present and I 
doubt its changed very recently). To edit it change the value for 
MessageStoreImpl::defJournalFlushTimeout in 

(There is a timer task per journal, though at present configured to use 
the same periodicity. So it would be possible without too much work to 
make it configurable on a per queue basis if anyone had the inclination).
