Without wanting to impose my method or reasoning here, I run my dev machine without swap, and I'd rather have the same for the cluster machines I access.

This is for academic use only. I know how much RAM my machine has, and if I oom, it usually isn't because I tried to squeeze in just a tiny bit too much data, but rather because I made some stupid mistake and keep allocating small chunks of memory very rapidly. On a system with even a moderate amount of swap, this makes everything grind to a halt, and it is usually much faster to just reboot the machine and deal with the problems later in the unlikely event that rebooting actually causes problems.

If you're running a single-(or close to)-purpose machine, then seeing an explicit memory usage limit on the main app could give you even better/faster results.
