Bug #5218: at_exit bug with exception handling

It seems that ruby 1.9.2 and later doesn't like exception handling in `at_exit` blocks and resets the exit code to 0.

Here is an example:

    #!/usr/bin/ruby

    at_exit do
      raise "X" rescue nil
    end

    at_exit do
      nil
    end

    at_exit do
      exit 1
    end

    at_exit do
      exit 2
    end
