+In fact, the datagrams are received.  The problem in this test case is
+the race condition between the async delegate performing the
+ReceiveFrom(), and the loop polling and creating a new buffer:
+
+Poll() says that data is there to be read
+A new buffer is created
+A new async thread is launched to read data into this buffer
+Poll() says that data is still there
+A new buffer is created
+The async thread reads the data into the old buffer
+The async thread calls the callback, which looks in the new buffer and
+doesn't find anything.
