示例1: getProbe

 function getProbe() {
   if (cmp.probeResult)
     return [cmp.probeResult];
   var _probe = jb_rx.Observable.fromPromise(ctx.run({$: 'studio.probe', path: ctx.params.path }));
   _probe.subscribe(res=>
     cmp.probeResult = res);
   // do not wait more than 500 mSec
   return _probe.race(jb_rx.Observable.of({finalResult: [ctx] }).delay(500))
     .catch(e=>
         jb.logException(e,'in probe exception'))
 }
