 Recognizing the need to write reactor-based GUI applications, the ACE
 community has created several reactor extensions for use with X Window
 System. Each of these extends the ACE_Select_Reactor to work with a
 specific toolkit. By using these reactors, your GUI application can remain
 single threaded yet still respond to both GUI events, such as button
 presses, any your own application events.
 .
 The ACE_QtReactor extends both the ACE_Select_Reactor and the Trolltech Qt
 library's QObjects class. Rather then using select(), the
 QtWaitForMultipleEvents() function is used.
