That may have been true in the late 80s and even early 90s but I'd have
thought FreeBSD, NetBSD and OpenBSD would have useable VMs by now.

I've vague recollections that these all originally used the VM from Mach
which did have problems at first.

I recall a more knowledgeable friend complaining about FreeBSD VM in 1994
or so.

I think the latter two use UVM and FreeBSD improved their Mach one (which
has a SunOS kvmish API anyway). I've not seen complaints about modern BSD.
