Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/45867 In most cases the lock ordering was hold a lock in local autograd and then hold a lock in DistAutogradContext. In case of `set_exception_without_signal` the lock order was in reverse and as a result we saw potential deadlock issues in our TSAN tests. To fix this, I removed the lock and instead just used std::atomic exchange. In addition to this, I fixed TestE2E to ensure that we use the appropriate timeout. TestE2EProcessGroup was flaky for these two reasons and now is fixed. ghstack-source-id: 113592709 Test Plan: waitforbuildbot.
