Description

Proper cancellation wasn't ever implemented for this code path, so if the wait time is set high, threads can get blocked indefinitely even if the coordinator cancelled the query.

I don't think it's hard to do the right thing - signal the filter and wake up the thread when the finstance is cancelled.
