I don't know what other people do, but I think the better option would be to set vm.swappiness to 0. Swap space is a good safety valve. You should never really have to use it, so a good way to detect that something is going really wrong and take action before it brings the system is down is by looking at when swap is busy filling up. Also if someone opens up an application that grabs huge chunks of RAM but leave a lot of it idle, and turn swap off completely, they should not be surprised. I don't know why people see this as a bug, but perhaps I've just been spending time in the UNIX family tree for too many decades.
