Summary:025281230de2e316f2770a2db71f8bec6fe43a07 changed `WebSocket` to fire both `onerror` and `onclose`.
However, `setupDevtools` assumed that only one of the two handlers would ever be invoked. When the handler is invoked, it re-invokes itself to keep a socket open. But since both handelrs are invoked, a series of closed or failed sockets can cause an exponential increase in sockets opened.
Symptoms of this bug include eventually reaching the maximum number of file descriptors allowed by the operating system, or a non-responsive system. Within React Native applications, symptoms include a failure to load resources from the React Native server or application crashes.
