Setting the swappiness to 0 delays any swaps until you've run out of
RAM completely and only then it starts writing to disk. As a result if
you have a lot of RAM, it's preferrable. On the other hand, when you
run out of memory, it will start heavily swapping immediately (depends
on how many processes want to grab the lot).

If you set it to a high number, the system will housekeep very often
and you will experience slow downs when you really don't need any (I
have 2GB free, why are you swapping 1GB, oh the wise kernel?)...
