Well said.
If your system doesn't have (enough) swapspace, OOM will start shooting
off processes, and your system will be rather slugish, i presume.

otoh, how can you be absolutely sure that your system won't _need_ any
swap? (besides starting up the system and watch it closely?)

There are a number of cases on would like to avoid swapping at all
costs. For instance when running from self-made dvd, or from SDD, where
swapping would means additional whereout of the sdd.
