That patch is a step forward if it's deemed OK by the powers that be.  
However, autovacuum would still need to be taught to handle simultaneous 
vacuums.  I suppose that in the interim, you could disable autovacuum 
for the problematic queue table and have cron issue a manual vacuum 
command for that table at the required frequency.

Anyone up for working on / testing / improving Hannu's patch?  I think 
it's beyond my skill set.
