Contrat

• GreenletExit inherits from BaseException rather than Exception, ensuring unhandled throw(GreenletExit) triggers finally clauses without getting intercepted by generic except Exception blocks, and returns the GreenletExit instance to the parent greenlet rather than raising an uncaught exception
• Calling g.throw(greenlet.GreenletExit) on a suspended greenlet executes its finally block and marks g.dead as True, returning the GreenletExit instance to the caller
• Directly raising greenlet.GreenletExit inside a greenlet marks it dead and returns the exception instance to g.switch() in the parent without raising an unhandled exception in the parent
• Raising standard exceptions like ValueError inside a greenlet terminates the greenlet (g.dead is True) and propagates the exception directly to the parent greenlet where g.switch() was invoked
