Synchronous Messaging

When doing long computations or blocking I/O, there is a real advantage to asynchronous messaging. But synchronous messaging should be the default, because it is so much faster. This is implemented by the Exchange class, which runs the EchoTimingTest at about 94 nanoseconds per message and the BurstTimingTest at about 98 nanoseconds per message.
