The admin requests are now processed in blocking mode. The timing out of connecttions is handled by a specific timeout thread that checks the state of each admin request. The simplification will help with the JSON parsing with PUT/POST commands. If non-blocking IO is used, the network reading code and JSON parsing needs a lot more work to handle partial reads. If the administrative interface requires higher performance and concurrency, a multi-threaded solution could be created.
