I've a pet peeve annoyance on pagers too: can they work without database 
queries yet? ;) About a dozen times over the years, I've had a need to 
use pagers, but couldn't becauase it wasn't a single query (or, worse, 
it was the result of a hook call, where there was no database activity 
going on at all...)
