Instance Method Details

#new ⇒ Object

The check runs BEFORE super (i.e. before allocate/initialize), so a violating class never gets partially constructed. This matters for FrameworkModule: its prepended Heartbeat starts a broadcasting thread inside initialize, and checking afterwards would leak that thread from a zombie instance whose .new appeared to fail.
