+/**
+ * XMLHttpRequest in workers
+ *
+ * XHR in workers is implemented by proxying calls/events/etc between the
+ * worker thread and an XMLHttpRequest on the main thread. The glue
+ * object here is the Proxy, which lives on both threads. All other objects
+ * live on either the main thread (the XMLHttpRequest) or the worker thread
+ * (the worker and XHR private objects).
+ *
+ * The main thread XHR is always operated in async mode, even for sync XHR
+ * in workers. Calls made on the worker thread are proxied to the main thread
+ * synchronously (meaning the worker thread is blocked until the call
+ * returns). Each proxied call spins up a sync queue, which captures any
+ * synchronously dispatched events and ensures that they run synchronously
+ * on the worker as well. Asynchronously dispatched events are posted to the
+ * worker thread to run asynchronously. Some of the XHR state is mirrored on
+ * the worker thread to avoid needing a cross-thread call on every property
+ * access.
+ *
+ * The XHR private is stored in the private slot of the XHR JSObject on the
+ * worker thread. It is destroyed when that JSObject is GCd. The private
+ * roots its JSObject while network activity is in progress. It also
+ * adds itself as a feature to the worker to give itself a chance to clean up
+ * if the worker goes away during an XHR call. It is important that the
+ * rooting and feature registration (collectively called pinning) happens at
+ * the proper times. If we pin for too long we can cause memory leaks or even
+ * shutdown hangs. If we don't pin for long enough we introduce a GC hazard.
+ *
+ * The XHR is pinned from the time Send is called to roughly the time loadend
+ * is received. There are some complications involved with Abort and XHR
+ * reuse. We maintain a counter on the main thread of how many times Send was
+ * called on this XHR, and we decrement the counter every time we receive a
+ * loadend event. When the counter reaches zero we dispatch a runnable to the
+ * worker thread to unpin the XHR. We only decrement the counter if the
+ * dispatch was successful, because the worker may no longer be accepting
+ * regular runnables. In the event that we reach Proxy::Teardown and there
+ * the outstanding Send count is still non-zero, we dispatch a control
+ * runnable which is guaranteed to run.
+ *
+ * NB: Some of this could probably be simplified now that we have the
+ * inner/outer channel ids.
