Overview
This class wrappers the communication channel built over the two inbound connections, allowing input and output to be split across both.

#close ⇒ Object
Closes the stream abstraction and kills the monitor thread.

#monitor_shell_stdout ⇒ Object
Funnel data from the shell's stdout to rsock
StreamAbstraction#monitor_rsock will deal with getting data from the client (user input). From there, it calls our write() below, funneling the data to the shell's stdin on the other side.
