Hi Mark,
 

I wanted to give another shot at removing the the default max-silent-time options in our scripts, so that everything can be consistent, but haven't got around it yet. I believe we shouldn't close this bug yet as it is still possible to get into the problem by running "guix environment", for example, which has a default max-silent-time value set to 1 hour.

Feel free to beat me to it if you have the bandwith.
