Of course, rereading what I just wrote suggests it may be possible to
unblock recv by constructing and sending a message it can act on
somehow, as a temporary band-aid.

I don't yet know how to do that, though, and in the meantime my muscle
memory stupidly killed the hung session, so it'll have to wait until the
next time it happens.

Thanks,
