-/**
- * \name Current dispatch and current context control variables
- *
- * Depending on whether or not multithreading is support, and the type of
- * support available, several variables are used to store the current context
- * pointer and the current dispatch table pointer.  In the non-threaded case,
- * the variables \c _glapi_Dispatch and \c _glapi_Context are used for this
- * purpose.
- *
- * In the "normal" threaded case, the variables \c _glapi_Dispatch and
- * \c _glapi_Context will be \c NULL if an application is detected as being
- * multithreaded.  Single-threaded applications will use \c _glapi_Dispatch
- * and \c _glapi_Context just like the case without any threading support.
- * When \c _glapi_Dispatch and \c _glapi_Context are \c NULL, the thread state
- * data \c _gl_DispatchTSD and \c ContextTSD are used.  Drivers and the
- * static dispatch functions access these variables via \c _glapi_get_dispatch
- * and \c _glapi_get_context.
- *
- * There is a race condition in setting \c _glapi_Dispatch 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 \c GL_TRUE, is
- * used to determine whether or not the application is multithreaded.
- * 
- * In the TLS case, the variables \c _glapi_Dispatch and \c _glapi_Context are
- * hardcoded to \c NULL.  Instead the TLS variables \c _glapi_tls_Dispatch and
- * \c _glapi_tls_Context are used.  Having \c _glapi_Dispatch and
- * \c _glapi_Context be hardcoded to \c NULL maintains binary compatability
- * between TLS enabled loaders and non-TLS DRI drivers.
