[not-my-profile]

Previously a script timeout error just displayed a stack trace without any information on the current timeout or how to change the timeout.

I think there are certain cases where it makes sense to make an exception (e.g. larger refactors). In this case though it was easy for me to split off the other change into #683.

(sidenote: the current dependencies CI failure does not appear to be related to the changes I made)
