add flag -D useSetTimeout=true for use setTimeout instead of setImmediate

[jdonaldson]

were you able to override the default event loop with setTimeout manually? Was chrome able to jit it efficiently?

ok with manually update nextLoop it works good. Thanks.

This is the code for manual nextLoop

    promhx.base.EventLoop.nextLoop = function(f) {
      untyped setTimeout(f,0);
    };
