/* a little bit of explanation for the folder_class->open 
 * method implementation : 
 * 
 * the proxy object "open" method is called by the client 
 * program in the main thread. This method creates a 
 * CamelOp object containing all the necessary informations 
 * to call the corresponding "open" method on the real 
 * folder object in the child thread. This CamelOp object 
 * is thus pushed in a queue in the main thread (see the 
 * CamelThreadProxy structure for more details). 
 * The operations in this queue are executed one by one
 * in a child thread. 
 * Once the "open" method of the real object is finished, 
 * it calls a callback. This callback is not the one supplied
 * by the client object. Instead, the _folder_open_cb()
 * function is called (in the child thread) which pushes
 * the real callback function in another operation queue.
 * The real callback is then called in the main thread.
