Well, I tried (unsuccessfully) to get the NeXT to recognize a
raw swap partition, so now I have an external 40Meg disk, with 
nothing but a swapfile (and /tmp) on it. 

Unfortunately, unless you can get mach_swapon to recognize
the raw partition, you will be going through the UNIX file system,
so your sector sizes may have little impact.

(BTW, if anybody *does* have swapping to a raw device working,
I would love to know what the command looks like!)

Regards,
