This is a slightly cleaned up version of the code that Devon created. All of eventhandler and socket in bin is designed for async communication only. Therefore, it does not make much sense to use it for something as simple as this. I have put the sync send and receive operations into DebuggerConnectionImpl instead of attempting to use the async Socket::Read and Socket::Write.
