Steps to reproduce:
Run while(1){} in the script console.
Actual results:
Entire browser froze.
Expected results:
Google Chrome spawns another subprocess (that uses an entire CPU core) but otherwise acts as if nothing happened. It might be nice if Firefox proved smarter than that by using the "slow script" dialog.
I have an unsimplified version that also eats all RAM, but simply detecting infinite loops should fix that as well.
