15815	Support memcached binary protocol in PyLibMCCache	Mike Tigas		"As per [http://sendapatch.se/projects/pylibmc/#example-usage] , enabling the binary protocol requires the `binary=True` argument to be passed into pylibmc.Client when it is initialized.

The binary protocol is available in Memcached 1.3+ and provides a performance boost in high-load circumstances: [http://www.slideshare.net/tmaesaka/memcached-binary-protocol-in-a-nutshell-presentation]

pylibmc ignores any unknown options passed into Client.behaviors (see below), so putting this in `OPTIONS` seems like the way to go.
