LGTM.
What's about Sergos'es naming proposal here [1]?

Sorry, I don't get how exactly to consider them, so I answer your
questions here. If it necessary I'll push them to the branch (yours or

Other changes are required only for parent process, looks obviously
as far as they are not added.

Tarantool stores the script name at index 0 in arg variable and
interpreter name at index -1, ignoring other CLI arguments between them.

Looks unnecessary and not such easy to configure, ignoring for now.
