This is really annoying me as well. I use a program for work that can occasionally use a lot of ram, while saving or interpolating for example. On my little MacBook Air with just 8GB of ram everything works fine, it just swaps a whole lot more for a short period. On my desktop with 16GB ram and Ubuntu oom just kills it, my workaround is the swapspace package which adds swap files under high load, works so far.
