Send a pickled string *packet* to the socket. This function allows for
partial sends which can happen when the network is busy.
+ .. method:: createSocket()
+
+ Tries to create a socket; on failure, uses an exponential back-off
+ algorithm. On intial failure, the handler will drop the message it was
+ trying to send. When subsequent messages are handled by the same
+ instance, it will not try connecting until some time has passed. The
+ default parameters are such that the initial delay is one second, and if
+ after that delay the connection still can't be made, the handler will
+ double the delay each time up to a maximum of 30 seconds.
+
+ This behaviour is controlled by the following handler attributes:
+
+ * ``retryStart`` (initial delay, defaulting to 1.0 seconds).
+ * ``retryFactor`` (multiplier, defaulting to 2.0).
+ * ``retryMax`` (maximum delay, defaulting to 30.0 seconds).
+
+ This means that if the remote listener starts up *after* the handler has
+ been used, you could lose messages (since the handler won't even attempt
+ a connection until the delay has elapsed, but just silently drop messages
+ during the delay period).
