I haven't tried VAX but have used the PDP-11 simulator in simh for
quite a while. On the PDP-11, simh originally used busy waits but
more recent versions can use blocking waits (at least in some
configurations). I doubt that the issue is related to the FreeBSD
port and suggest you check the simh documentation and/or raise an
issue with simh.
