  "message": "Handle possible deadlocks and hangs during PeerConnection teardown\n\nAddress two issues related to thread shutdown and teardown when the\ntarget thread (network/worker) has been instructed to quit before the\nPeerConnection destruction has completed:\n\n1. In ScopedOperationsBatcher::Run(), if the target thread drops tasks\n(e.g., because it is quitting), the loop would previously run infinitely\nbecause task_idx did not advance. We now detect this by verifying that\ntask_idx has progressed after the BlockingCall, and abort if it has not.\n\n2. In MethodCall::Marshal and ConstMethodCall::Marshal, if the target\nthread drops the task because it is quitting, the calling thread would\npreviously hang forever because event_.Set() was never called. We now\nuse absl::Cleanup to ensure the event is set on task destruction.\n\nBug: b/515407473\nChange-Id: Iea8ec32b6a9e9850983ed563db07b5c386ad834d\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/479140\nReviewed-by: Danil Chapovalov \u003cdanilchap@webrtc.org\u003e\nCommit-Queue: Tomas Gunnarsson \u003ctommi@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#47930}\n",
