I'm running the following setup:

 > gmirror status
       Name    Status  Components
mirror/gm0  COMPLETE  ad0
                       ad2

 > swapinfo

/dev/mirror/gm0s1b   1048576      784  1048576     0%

devfs on /dev (devfs, local)
/dev/mirror/gm0s1d on /tmp (ufs, local, soft-updates)
/dev/mirror/gm0s1e on /usr (ufs, local, soft-updates)
devfs on /usr/var/named/dev (devfs, local)

Can someone confirm if this is not what should be done? It has appeared 
to work fine (having swap mirrored is a good thing from a keeping the 
system alive point of view), and I would be interested to hear why it 
shouldn't be done.

Cheers,
