// OpcThrd.cpp 
// 
//   This file contains a sample implementation of 
//   Background/Async handling for the OPC server. 
// 
// Note that this is a VERY simple implementation intended 
//   (like the rest of this code) to show the basic principles. 
//   A 'real' imlementation would probably be much more 
//   sophisticated and use the apartment or free threading model 
// 
// Also this code is currently NOT threadsafe at this time when used InProc 
//   It has some minimal critical section logic to deal with the more 
//   obvious issues. 
//   But the client can still change things inside the server and groups 
//   while this thread is running which can potentially cause problems.
