Insane high cpu usage when blocking mob spawning

[Tencao]

It seems that rather than disabling it attempting to spawn mobs, it instead just keeps blocking every single attempt, which when covering a large area, causes massive lag and cpu usage.

There's really not a good way to block mob spawning, as minecraft and mods will just haphazardly try to spawn them if they feel like it.

If you think there's a much better method, please let me know.

This sort of thing usually needs forge-level tinkering to accomplish. CustomMobSpawner and JustAnotherSpawner handle mob spawning (and denial thereof), but don't involve regions or permissions. This seems to be uncharted territory for Sponge.
WorldGuard (for Bukkit) has the customisable flag block-creature-spawn: under mobs.

I'll keep this open, but i don't think there's a good solution any time soon.

Where's the code for denying mob spawns, so I can also help find a solution?
