		@subsection How MySQL uses DNS

		When a new threads connects to @code{mysqld}, @code{mysqld} will span a
		new thread to handle the request. This thread will first check if the
		hostname is in the hostname cache. If not the thread will call
		@code{gethostbyaddr_r()} and @code{gethostbyname_r()} to resolve the
		hostname.

		If the operating system doesn't support the above thread-safe calls, the
		thread will lock a mutex and call @code{gethostbyaddr()} and
		@code{gethostbyname()} instead. Note that in this case no other thread
		can resolve other hostnames that is not in the hostname cache until the
		first thread is ready.

		You can disable DNS host lookup by starting @code{mysqld} with
		@code{--skip-name-resolve}. In this case you can however only use IP
		names in the @strong{MySQL} privilege tables.

		If you have a very slow DNS and many hosts, you can get more performance by
		either disabling DNS lookop with @code{--skip-name-resolve} or by
		increasing the @code{HOST_CACHE_SIZE} define (default: 128) and recompile
		@code{mysqld}.

		You can disable the hostname cache with @code{--skip-host-cache}. You
		can clear the hostname cache with @code{FLUSH HOSTS} or @code{mysqladmin
		flush-hosts}.

		If you don't want to allow connections over @code{TCP/IP}, you can do this
		by starting mysqld with @code{--skip-networking}.
