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.
