+ * 2001/01/16 - added dispatch override feature for Mesa 3.5
+ * 2002/06/28 - added _glapi_set_warning_func(), Mesa 4.1.
+ * 2002/10/01 - _glapi_get_proc_address() will now generate new entrypoints
+ * itself (using offset ~0). _glapi_add_entrypoint() can be
+ * called afterward and it'll fill in the correct dispatch
+ * offset. This allows DRI libGL to avoid probing for DRI

+ * thread-safe dispatch table. These dispatch routines would call
+ * \c _glapi_get_dispatch to get the actual dispatch pointer. In this
+ * setup \c _glapi_Dispatch could never be \c NULL. This dual layered
+ * dispatch setup performed great for single-threaded apps, but didn't
+ * perform well for multithreaded apps.
+ *
+ * In the new mechansim, there are two variables. The first is
+ * \c _glapi_DispatchTSD. In the single-threaded case, this variable points
+ * to the dispatch table. In the multi-threaded case, this variable is
+ * \c NULL, and thread-specific variable \c _gl_DispatchTSD points to the
+ * actual dispatch table. \c _glapi_DispatchTSD is used to signal to the
+ * static dispatch functions to call \c _glapi_get_dispatch to get the real
+ * dispatch table.
+ *
+ * There is a race condition in setting \c _glapi_DispatchTSD to \c NULL.
+ * It is possible for the original thread to be setting it at the same instant
+ * a new thread, perhaps running on a different processor, is clearing it.
+ * Because of that, \c ThreadSafe, which can only ever be changed to
