For the record, I asked a Solaris kernel engineer about that shm_open() problem and learned that a fix shipped about a month after we had this discussion (though I haven't tested it myself): https://twitter.com/casperdik/status/1730288613722562986 I also reported the issue to illumos, since I'd like to be able to revert 94ebf811 eventually...: https://www.illumos.org/issues/16093
