/*
 * Structure of the Haiku GUI code:
 *
 * There are 3 threads.
 * 1. The initial thread. In gui_mch_prepare() this gets to run the
 *    BApplication message loop. But before it starts doing that,
 *    it creates thread 2
 * 2. The main() thread. This thread is created in gui_mch_prepare()
 *    and its purpose in life is to call main(argc, argv) again.
 *    This thread is doing the bulk of the work.
 * 3. Sooner or later, a window is opened by the main() thread. This
 *    causes a second message loop to be created: the window thread.
 *
 * == alternatively ===
 *
 * #if RUN_BAPPLICATION_IN_NEW_THREAD...
 *
 * 1. The initial thread. In gui_mch_prepare() this gets to spawn
 *    thread 2. After doing that, it returns to main() to do the
 *    bulk of the work, being the main() thread.
 * 2. Runs the BApplication.
 * 3. The window thread, just like in the first case.
 *
 * This second alternative is cleaner from Vim's viewpoint. However,
 * the BeBook seems to assume everywhere that the BApplication *must*
 * run in the initial thread. So perhaps doing otherwise is very wrong.
 *
 * However, from a B_SINGLE_LAUNCH viewpoint, the first is better.
 * If Vim is marked "Single Launch" in its application resources,
 * and a file is dropped on the Vim icon, and another Vim is already
 * running, the file is passed on to the earlier Vim. This happens
 * in BApplication::Run(). So we want Vim to terminate if
 * BApplication::Run() terminates. (See the BeBook, on BApplication.
 * However, it seems that the second copy of Vim isn't even started
 * in this case... which is for the better since I wouldn't know how
 * to detect this case.)
 *
 * Communication between these threads occurs mostly by translating
 * BMessages that come in and posting an appropriate translation on
 * the VDCMP (Vim Direct Communication Message Port). Therefore the
 * actions required for keypresses and window resizes, etc, are mostly
 * performed in the main() thread.
 *
 * A notable exception to this is the Draw() event. The redrawing of
 * the window contents is performed asynchronously from the window
 * thread. To make this work correctly, a locking protocol is used when
 * any thread is accessing the essential variables that are used by
 * the window thread.
 *
 * This locking protocol consists of locking Vim's window. This is both
 * convenient and necessary.
