If we get to that stage, something is _badly_ _badly_ _badly_ _badly_ wrong. Rather than papering over the problem (assuming it is actually large enough to notice at runtime, which I'm not entirely convinced it is) and adding yet more alternate codepaths no-one will probably ever test, we could just make accel acceptably small ...
