synchronize.jsの注意点

var sync = require('synchronize');

sync.fiber(function() {
  try {
    sync.await((function(defer) {
      console.log("await 1 start");
      setTimeout(function() {
        console.log("await 1 end");
        try {
          sync.await((function(defer2) {
            console.log("await 2 start");
            setTimeout(function() {
              console.log("await 2 end");
              defer2(null, 'ok');
            }, 1000);
          })(sync.defer()));
          console.log("await 2 over");
          defer(null, "ok");
        }
        catch(e) {
          console.log("await 2 error", e);
          defer(e, null);
        }
      }, 1000);
    })(sync.defer()));
  } catch(e) {
    console.log("await 1 error", e);
  }
  console.log("await 1 over");
});

% node sync_test.js
await 1 start
await 1 end
await 2 error [Error: no current Fiber, defer can'b be used without Fiber!]
await 1 error [Error: no current Fiber, defer can'b be used without Fiber!]
await 1 over
