gevent compatible Memcache client

I have been looking for a memcache client that plays well with gevent, and I stumbled upon one today:

https://github.com/esnme/ultramemcache

It’s written and maintained by the good folks at ESN.me.  They built Battlelog, the social network for Battlefield 3, using gevent and this memcache client.  They also released a gevent-compatible MySQL driver and a few other interesting python projects.

I’ll be doing load/stress testing with various different clients and setups for flask/gevent in the coming weeks, and I’ll post my findings here.
