Use case of removing swap devices at runtime

Once you're using swap, response will be similar to treacle, so I would have thought optimising for speed would be a very definite benefit!

And while swap devices may be static on personal computers, I would have thought cloud computing is more likely to take the attitude "create swap files as required when memory usage rises", rather than pre-emptively allocate it. These things have a cost - why pay it when you don't need to?
