	# Normally tor uses a bundled libevent fragment to provide
	# asynchronous DNS requests.  This is generally a bad idea, but at
	# the moment the official libevent does not have the 0x20 hack, so
	# anonymity is higher with the bundled variant.  Remove patch as
	# soon as upstream has installed the autoconf option to use
	# system's libevent (0.2.1 or later)
