+            receive events and all socket operations will time out.
+            BTW, the main thread must not be stopped using sleep or block
+            on a semaphore (a bad idea in any case) or socket operations
+            will time out.
+
+            On the Mac side, Initialize() stores a pointer to the CFRunLoop for

+            adding event notifications to the "Current" loop would have no
