Immutable-js: infinite loop hashing Infinity

[colbyr]

It seems that causing Immutable to hash Infinity triggers an infinite loop (makes sense I suppose :smirk:).

I can reproduce in Chrome and Firefox from the console on the doc site.

m = Immutable.Map({test: Infinity});
m.hasCode() // spins forever

I haven't really dug into the hasher. If it's not possible to hash infinity, I'd at least expect to see an exception.

Haha, nice one. If hashing Infinity takes forever, does hashing -Infinity... reverse time? Let's not even try it just to be safe ;)

Good find.
