Is it means the control of timing still depended on the user?

time-slicing/index.js

Lines 8 to 10 in f75cf7a

	do {
	res = gen.next()
	} while(!res.done && performance.now() - start < 25);

As the code shows, ts function just runs the user's function gen.next(), but don't compute its time cost. So if gen.next() spends too much time, it still blocks the browser, right?

I think, the gen.next function may implement a cancel method, when ts func finds it costs too much time, then call the cancel method to cancel the running, is that possible?

Or implement it inside ts function.

@musicq Hahaha. real a great idea. ts seems cannot cancel the user's method, so you are right, the control is really in the user.

In addition, performance.now() - start already contains the running time of gen.next().
