+/*
+* 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.
