* This means that the library is called at process shutdown, and cannot be unloaded beforehand.
* PHP tries to unload modules after every request [dl()'ed modules], and right before the
* process shuts down [modules loaded from php.ini]. This results in a segfault for this module.
* By NULLing the dlopen() handle in the module entry, Zend omits the call to dlclose(),
* ensuring that the module will remain present until the process exits. However, the functions
* and classes exported by the module will not be available until the module is 'reloaded'.
* When reloaded, dlopen() will return the handle of the already loaded module. The module will
* be unloaded automatically when the process exits.
