* This test application tests the state of WFMO_Reactor when
* exceptions occurs when executing user callbacks.
*
* The thread count in WFMO_Reactor is used to ensure that state of
* WFMO_Reactor is not fouled up when exceptions occur in user code.
* This example also shows how to write event loops that survive
* user exceptions
