Swapping to a file is really slow and should only be done if absolutely
necessary since every read/write has to go through the filesystem code
which it doesn't do if done via a swap slice.

Good point.  It's been several years and back on v5 or 6 when I did something like this.  If there's unpartitioned space on the drive, can one add a secondary swap partition real-time?  I forget what I did here - I'm sure I followed what's in the handbook re swap space.  Probably did a swap file...
