Sure. And I'm sure some programs make use of that. I'm not aware of any, though, so I presume it isn't very common. The random collection of scripts and utilities our build system runs doesn't even report OOM in any sensible way. Fortunately it is trivial to find out after the fact if that was the case (and like I said before, things slowing down once physical memory is getting too scarce is pretty good indicator that something is wrong).
