* The main driver for this change was to make the read from a.newFragmentCh timeout quickly rather than waiting for the test timeout (much longer). While testing the change I observed a panic during shutdown, but it was swallowed and moreover there was no stack trace so it wasn't obvious. I'm hoping we can get rid of the recover, so I fixed the issue in the activitylog tests that needed it.
