#at_exit_preserving_exit_status(&block) ⇒ Proc

Alternate implementation of at_exit that preserves the exit status (unless you call exit yourself and an error is raised).

The initial driver for this was that using at_exit to clean up global resources in RSpec tests, RSpec's exit status would be lost which means CI processes and such were unable to tell whether there were test failures.

Returns:

  • (Proc) —

    Whatever at_exit returns.
