No, you have it backwards. ACE_Select_Reactor can't call
run_reactor_event_loop() in multiple threads, but ACE_WFMO_Reactor and
ACE_TP_Reactor can be called in multiple threads.

The documentation for each reactor should explain whether its
handle_events() can safely be run in multiple threads (if not, the
documentation should be updated). As far as I know, only the
ACE_TP_Reactor and ACE_WFMOReactor can be run in multiple threads.
