(chuckles) - sure no-one likes to wait, but for DSS type queries there 
is usually waiting involved anyway. In addition the aim of resource 
scheduling is to improve the throughput by utilizing the available 
resources more carefully, so on average there should be less waiting.

I do agree that being able to send a "query is queued" client message 
type would be good, but the level of impact on existing client 
libraries/drivers makes that not so nice.
