I ran into a critical bug when using the inquirer package when zone.js is imported.
After reading a bunch of source code, I assembled the following code snippet to reproduce the underlying issue with rx Observables and zone.
var createInterface = require('readline').createInterface;
var Observable = require('rx').Observable;
require('zone.js');
var rl = createInterface({ terminal: true, input: process.stdin, output: process.stdout });
var keypress = Observable.fromEvent(rl.input, 'keypress');
var line = Observable.fromEvent(rl, 'line');
keypress.takeUntil(line).toPromise();
When running the above code as a node script and pressing the 'enter' key as input, the following error occurs:
Error: eventTask 'ReadStream.addListener:keypress': can not transition to 'running', expecting state 'scheduled', was 'notScheduled'.

A proper fix is obviously ideal, but please let me know if there is any quick code fix I can do before the real fix is merged.
