- * This looks a lot more complicated than it is, and than you'd think
- * it would need to be.  There is however, method to the madness.
- *
- * The code most cope with being called from any thread at any time,
- * recursively from the main thread, and then serialising every
- * request so that sane and correct values are always returned, and
- * duplicate requests are never made.
- *
- * To this end, every call is marshalled and queued and a dispatch
- * method invoked until that request is satisfied.  If mainloop
- * recursion occurs, then the sub-call will necessarily return out of
- * order, but will not be processed out of order.
