The system now processes through all the PAM infrastructure, which
provides a bunch of additional functionality. Whether that
functionality is worthwhile is certainly a valid discussion.

It makes heavy use of shared objects, which I believe is also a
significant performance hit on current VAX.

It would be interesting to see what profiling might report for a login sequence.

The sun2 port builds with NOPIC= so everything is static linked. It
would also be nice to compare the performance for a NOPIC= build of
NetBSD/vax (I'm just started a netbsd-6 static vax build to see if it
completes, but I don't really have an ideal machine on which to test)
