   > Thanks for the update, the round-2 items are all addressed and the touched 
test classes pass locally on `45b20278b8`.
   > 
   > Two remaining issues I think are blocking (see inline): the bytes-guard 
resume on the `closeDirtyAndRevive` path can crash the thread, and with only 
the deprecated config set the legacy resume defeats the bytes cap every 
iteration.
   > 
   > Separately, given this feature was reverted in 2022 for a performance 
regression with the same pause-all-non-empty algorithm, could you post a simple 
throughput comparison against trunk (default config, and a cap small enough to 
trigger pausing) before we merge? Also please retarget the deprecation/upgrade 
notes to 4.5 since 4.4 has branched.
   
   Thankyou @frankvicky for the thorough review. Both blocking issues are 
addressed including other comments.
   Ptal.
