// test_timeout.cpp
//
// = DESCRIPTION
//
// This example application shows how to write event loops that
// handle events for some fixed amount of time. Note that any
// thread in the Proactor thread pool can call back the handler. On
// POSIX4 systems, this test works only with POSIX_SIG_Proactor,
// which can work with multiple threads.
