Thank you for working on this! These are very nice speedups.

+    #swapon /dev/sd0j # fails with ENXIO... what am I missing?

I think I found the problem, sd0j's fstype is not a swap. It worked like that:

$ disklabel -E sd0
$ umount /usr/obj
$ disklabel -E sd0 # prompts are: m -> j -> \n -> \n -> swap -> w -> q
$ disklabel -E sd0
$ swapon /dev/sd0j # runs successfully
