// 1. It kicks off a different thread pool thread every time data is received. As such there is no
// way to order the input.
// 2. The shell in Linux keeps a queue of input. If a component only obtains the input through the
// output received event, then nothing will ever drain the output.
//
// Suggested fix: Add a ReadLine async method to the shell and remove the output received event
// TODO: rajkumar42, this breaks when logging in as root.
