The TpfgPalmPollingThread is a thread class designed to keep the connection to the Palm active whilst you are doing intensive tasks that preclude you from making regular calls to the Palm in your main thread.
For example, suppose your conduit synchronises across the Internet, and you make a system call to download an XML document containing all the changes. If there were a lot, it would be possible for the Palm connection to die. By using this thread, you can keep the connection active.
Returns true if the thread has terminated.
Locks the thread, preventing it from functioning until the Unlock method is called. This is recommended if you plan to make calls to the Palm API yourself, and don't want to go to the bother of destroying the thread.
