Something like this could be used to decide whether or not to flush unimportant in-memory caches, compact data structures, etc., or just give up and exit.

That's a nice idea, but unless the requested allocation was fairly large, there's a good chance you don't have room to allocate anything more. That may make it a bit tricky to do a compaction operation. But if there's some sort of "automatically freeable memory" (simple example: exception-triggered stack unwinding results in a whole bunch of locals disappearing), and you can stay within that, then you might be able to recover. Would require some tightrope-walking in the exception handler, but ought to be possible.
