 As mentioned in [comment:5:ticket:16066] and [comment:5:ticket:29679] we
 should consider using `ignore_user_abort()` to prevent the potential issue
 of an upgrade process being aborted mid-way due to a browser cancellation.

 This could be called before any update activity starts, or perhaps only
 after actual changes start happening (ie. after the zipfile download,
 before the file alterations).
