test_callback (tests.test_events.PollClientTestCase) …
This test gets stuck for an apparently infinite amount of time on my system, also with slowly increasing memory usage. Seems to be a race condition involving PollClient. Adding a time.sleep(0.1) before `self.logs.add(test_log.copy())` (https://github.com/curoverse/arvados/blob/0b5d04beb288175a285c36a38f255399dfe7d0d7/sdk/python/tests/test_events.py#L338-L339) avoids the issue on my system.

I suspect you may be able to reproduce this bug if you run the tests on a system with only one CPU. I had been running arvbox on a VirtualBox VM configured to have only one CPU.

I had a chance to test the unpatched version of this test over the weekend and it appears that it hangs on test_callback for me even with 4 CPUs, so that doesn't explain the difference.
