 * when threads get created, we simply pick them up when we see them the
 * first time.)

 * @returns Success indicator.
 * @param   hInstDll        The instance handle of the DLL. (i.e. the module handle)
 * @param   fdwReason       The reason why we're here. This is a 'flag' for reasons of
 *                          tradition, it's really a kind of enum.
 * @param   pReserved       Reserved / undocumented something.
