Err, I think I was unclear---the "bug" I was talking about was letting
scheduler queries get in the way of emptying video buffers.  (E.g., I
wasn't saying that 20-30s queries were a bug.  While faster is always
better, I don't have a problem with long scheduler queries as long as
they don't hang captures.)

So I think we're in agreement here... :)
