[PG NCCL] catch cuda lib runtime error - driver shutting down (#74258) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/74258 There is a case when PG cleanup thread checks cuda event status after cuda runtime library has been unloaded. When that happens, it would leads to a "driver shutting down" error. This issue usually happens when cuda API is called in global or static object destructor.
