FTR I noticed that my animal elver hadn't reported for a while and logged and found it locked up, a bit like that, but in test_shm_mq rather than PHJ. It's FreeBSD 13.1 on a fairly fast 16 way amd64 (in a jail), and it was testing REL_12_STABLE, so using poll() for WaitEventSetWaitBlock(). When I connected a debugger then disconnected, it was unblocked and continued. Unfortunately I didn't get any new information :-(
