Existing programs work the - same since giving the Reactor's constructor a 0 value - (which is the default argument, BTW) instructs it to behave - as before.

To test the "multiple handlers per-signal semantics", you - need to pass the constructor/open method of the ACE_Reactor - a pointer to a an instance of ACE_Sig_Handlers (note the - plural "s"). ACE_Sig_Handlers is a class that derives from - ACE_Sig_Handler. The difference between these two classes - is that (1) ACE_Sig_Handlers::register_signal allows - multiple ACE_Event_Handlers to be registered per-signal and - (2) it enables SA_RESTART by default.
