Calling it twice in a row makes it never resolve. The actor implementation could probably be made more resilient, but memoizing it on the front would probably help reduce the number of request we are doing. This issues appears with the first changeset, parellizing the call to ResourceCommand._startListening. Differential Revision: https://phabricator.services.mozilla.com/D114413
