* Process the current thread's event queue, calling event handlers until

* The name 'enterNestedEventLoop' may be misleading if read too literally.
* This method loops calling event handlers until one asks it to stop, and
* then returns. So by that point, the nested event loop has been not only
* entered, but also run and exited.
*
* When enterNestedEventLoop calls an event handler, that handler may itself
* call enterNestedEventLoop, and so on, so that there may be arbitrarily
* many such calls on the stack at the same time.
*
* We say an enterNestedEventLoop call is "running" if it has not yet been
* asked to return, or "stopped" if it has been asked to return once it has
* finished processing the current event.
*
* @param requestor A token of the caller's choice to identify this event
* loop.
*
* @return depth The number of running enterNestedEventLoop calls
* remaining, now that this one has returned.
*
* (Note that not all calls still on the stack are
* necessary running; exitNestedEventLoop can ask any
* number of enterNestedEventLoop calls to return.)
