[Snek] Stopping a runaway program

[Misha Gusarov]

Hi.

How should a runaway Snek program be stopped?

The problem I'm trying to solve is the following: I'd like to run a 
program from "EEPROM"
on start on Lego EV3, but I find that even trivial

> while True: print("hello world")

can't be stopped via "serial" (actually network) – snek is busy 
outputting data, and does
not stop to read Ctrl-C from stdin.

If that does not work, then running anything at startup is a recipe for 
disaster: the only
way to clear a bad for program will be SSHing to the EV3 and removing 
the stored program.

Best,
Misha.
