It seems that the behaviour on macOS means that sometimes a MultiReceiver attempts to use a missing IpcReceiver. Presumably this doesn't happen on Linux because the relevant message(s) happen to have found their way to the relevant standard channel and can be accessed from there rather than needing to call MultiReceiver.

The fix is probably to allow MultiReceiver to either contain an IpcReceiver or refer to a MultiReceiverSet. Then the corresponding functions can be added to MultiReceiverSet and called as needed.

After making some changes (commit 153db473d4), the test failures have turned into the following hangs:
