-block: leave the request timeout timer running even on an empty list
-
-For sync IO, we'll often do them serialized. This means we'll be touching
-the queue timer for every IO, as opposed to only occasionally like we
-do for queued IO. Instead of deleting the timer when the last request
-is removed, just let continue running. If a new request comes up soon
-we then don't have to readd the timer again. If no new requests arrive,
-the timer will expire without side effect later.
-
-This improves high iops sync IO by ~1%.
