We found that the QIO channel coroutine could not be awakened in some
corner cases during our stress test for COLO.
The patch fixes as follow:

Adaptive polling measures the execution time of the polling check plus
handlers called when a polled event becomes ready. Handlers can take a
significant amount of time, making it look like polling was running for
a long time when in fact the event handler was running for a long time.

These patches are taken from my old patches and feedback of
my series "block layer: split block APIs in global state and I/O".
