* The idea of _nss_cache_cycle_prevention_function is that nsdispatch will

* the caching daemon. So, if it exists, nsdispatch won't try to connect to
* the caching daemon and will just ignore the 'cache' source in the
* nsswitch.conf. This method helps to avoid cycles and organize
* self-performing requests.
