> There is a race condition where concurrent RPCs can register with the ClientRequestState after Finalize has been called. This causes the DCHECK(pending_rpcs_.empty()) since these RPCs are not unregistered in Finalize() as expected.
> Issue reproduces with ASAN builds running tests/hs2/test_hs2.py::TestHS2::test_concurrent_unregister in a loop.
