Instance Public methods
Initiates the termination of the Ruby script by raising the
SystemExit exception. This exception may be caught. The
optional parameter is used to return a status code to the invoking
environment. true and FALSE of status
means success and failure respectively. The interpretation of other
integer values are system dependent.

(see Kernel::at_exit) and runs any object finalizers (see ObjectSpace.define_finalizer).
