// For polling transports in a situation when in the message callback,
// new message is being send. If the sending connection was started
// before receiving one, it is possible to saturate the network and
// timeout due to the lack of receiving socket. To avoid that we delay
// sending messages by some small time, in order to let receiving
// connection be started beforehand. This is only a halfmeasure and
// does not fix the big problem, but it does make the tests go more
// stable on slow networks.
