Detailed Description

Helper binary that is started from a remote interpreter loop to start a local interpreter loop.

This helper monitors for three termination events. They are: (1)The stdin of the helper is closed for reading; (2)the helper received SIGTERM/SIGINT; (3)the local loop crashed. In case of events 1 and 2 the helper kills the interpreter loop. When the interpreter loop crashed (event 3), the helper should send a SIGTERM to its own process group; this behaviour will help terminate any child processes the loop has started and prevents them from leaking and running forever.
