A little bit --- the timeout won't actually kill the query until the
next time control reaches a CHECK_FOR_INTERRUPTS macro that's not inside
a critical section. We've had issues in the past with particular code
paths that failed to include such a check in a long-running loop, and
there might still be some left. But by and large, it won't take very
long for the query to notice the interrupt.
