- """
- Implementation of the resolver API using native threads and native resolution
- functions.
-
- Using the native resolution mechanisms ensures the highest
- compatibility with what a non-gevent program would return
- including good support for platform specific configuration
- mechanisms. The use of native (non-greenlet) threads ensures that
- a caller doesn't block other greenlets.
-
- This implementation also has the benefit of being very simple in comparison to
- :class:`gevent.resolver_ares.Resolver`.
-
- .. tip::
-
- Most users find this resolver to be quite reliable in a
- properly monkey-patched environment. However, there have been
- some reports of long delays, slow performance or even hangs,
- particularly in long-lived programs that make many, many DNS
- requests. If you suspect that may be happening to you, try the
- dnspython or ares resolver (and submit a bug report).
