In multi-backend case there always a chance for client to miss a working backend among not responding.
Assuming memcached is up and running on localhost:11211:
import memcache
import random
cl = memcache.Client(['localhost:11211', 'localhost:11212', 'localhost:11213', 'localhost:11214'])
while cl.set(str(random.random()), 1): pass
'while' must be an infinite loop since cl.set() returns True on success but it exits in milliseconds instead.
Bug may be fixed by changing backend selection logic, patch attached. |

The other way is to use https://github.com/linsomniac/python-memcached2/ as linsomniac suggested: https://github.com/linsomniac/python-memcached/pull/57 |
