In #1496, we observed a situation where the `work()` method crashes after `.subscribe()`, but prior to the `try/except` block which normally cleans up after `.subscribe()`. Specifically, `.subscribe()` launches a thread in non-daemon mode. Because of that setting, Python will keep the calling worker process active, even if the main thread has crashed. This resulted in a syndrome where a worker process was running, but doing no work. The change launches this thread in daemon mode, i.e. prevents a "zombie" pubsub thread from keeping the process up. (An additional change we could make, discussed in #1496 but deferred, would be to improve the error handling/trapping scope in `.work()` such that all failures trigger resource cleanup.) |
