767     * When the Interbase client API library libgds.so is first loaded, it registers a call to
768     * gds__cleanup() with atexit(), in order to clean up after itself when the process exits.
769     * This means that the library is called at process shutdown, and cannot be unloaded beforehand.
770     * PHP tries to unload modules after every request [dl()'ed modules], and right before the
771     * process shuts down [modules loaded from php.ini]. This results in a segfault for this module.
772     * By NULLing the dlopen() handle in the module entry, Zend omits the call to dlclose(),
773     * ensuring that the module will remain present until the process exits. However, the functions
774     * and classes exported by the module will not be available until the module is 'reloaded'.
775     * When reloaded, dlopen() will return the handle of the already loaded module. The module will
776     * be unloaded automatically when the process exits.
