…2681) Summary: Pull Request resolved: #52681 Changelog: [internal] In the original change I made in D78418504 / #52645 I made 2 mistakes: 1. Used a lock that would try to re-lock on itself without it being recursive (which would cause a deadlock). I didn't see that because when testing I didn't hit the case where we'd exhaust the options. 2. The `attemps` variable wasn't incremented, so we never left the loop in case of exhaustion. This propagates a flag to `tryCommit` to indicate we've already locked on the commitMutex_ so we don't need to lock again in that case and increases the counter, fixing the issue.
