That's right, it doesn't get horrific until you use goto or yield (which don't exist in Javascript so they have to be emulated).

Some browsers, and ES Harmony, have yield. You could add a compiler switch to use native support, although only Firefox seems to support this just now.

Curious to see how you managed the emulation - splitting up a function? Web workers? :)

for (;;), continue and switch.
