i'd take mild exception to that position.  if something is a
selectable option in busybox, then it's reasonable for users to think
it's a well-supported feature.  to suggest that, if they pick V0,
they'll "get what they deserve" is not terribly compassionate and
probably wouldn't go down well with users.

if a feature in BB is not actively supported or might cause all kinds
of grief, then it really should be removed and not left as a land
mine waiting for someone to trip over.  frankly, i see no real value
to V0 swap support.

the 2.2 kernel uses swap V1 so dropping V0 wouldn't affect this.
