Well, it was a memory leak, filling more and more resident memory, leaving less and less for other uses. I didn't investigate, but I'm guessing not cache.

User space thing really: you could add an option to swapoff(8) to loop retrying (well, I think it would need to fork off a child to do the sys_swapoff, fork another when that one gets OOM-killed; a bit messy, I agree).
