Review comment:
Not really. The problem is that there are no common parts between the
"in_container" and "out_container" stuff. We are even excluding the
non-in-container scripts when we prepare the images, to make sure that what we
run outside of the container is not run inside (by default). I think it's
important to keep that separation. This is a really small piece of code that
does not really require maintenance - kind of a "util" class (and a nice one to
have at that - since we already use traps in several places and traps -
unfortunately - in shell scripts are simply replacing previous traps rather
than add to them.
