// = DESCRIPTION
//
// This test application tests a wide range of registration,
// suspension, resumption, and removal of events from Reactor.
//
// The application initially registers two events with Reactor. A
// auxiliary thread is created to do the signaling on the
// events. When the first event is signaled, the event is suspended
// from Reactor. The event is then signaled again, but is "lost"
// since the handler has been suspended. When the second event is
// signal, the first event is resumed and the second is
// suspended. When the first event is signaled again, both events
// are removed from Reactor.
//
// This test shows off the following features of Reactor:
// - Registration
// - Suspension
// - Resumption
// - Removal (while active and while suspended)
//
