[Bug]: Switching to bash lang under mux currently hangs on my system

[jmetz]

What went wrong?

The shrs_example program maxes out the CPU and the terminal oddly accepts input but won't do anything.

Spawning shell used is fish.

Can type
But nothing happens, and the process just uses a bunch of cpu time

Ah, i think the bash lang work is still work in progress. The best working language is python currently, and we just need to abstract some of the mechanisms we use to also work with bash.
