Profiling data written to the outgoing socket, from the agent controller to the workbench, is currently unbuffered. This means that 20,000-25,000 single 100-byte messages per second are being sent out one-at-a-time, rather than together. This imposes a major performance penalty on profiling overhead and workbench processing speeds.

Fix is to wait for a certain amount of data to be available, and write it all at once, rather than writing each message separately. This also requires us to maintain a thread which ensures that data will not wait longer than a fixed amount to be sent.
