Just keep enough swap around. How hard can that be ?
Really, it's not like a memory leak or something. It's just "late reclaim".
If Linux didn't do over-commit, you wouldn't have been able to run that job anyway.
It's not a bug. It's a feature. It only breaks systems that are run with "too little" swap, and the only difference from 2.2 till now is, that the definition of "too little" changed.
