We've got a race where we'll start a thread when we need one, even if we've already started a thread. This changes TaskRunner's behavior to never add a thread if we're still waiting for a recently-added one to start running. This is intended to reduce the number of threads contenting for the TaskRunner lock as reported in this issue: #8388

Hi @swankjesse. Would it please be possible to initiate a 4.x release that includes this fix? The latest 4.x release is still 4.12.0 from 2023-10-16. Thank you. |
