Infinite loop on EISCONN

[alexey74]

Hello, I gave this library a try with my eventlet-based workers, and it appears to be OK most of the time, but sometimes the workers begin consuming 100% CPU and when I strace them I see that they are infinitely looping in connect() to a memcached server because of EISCONN:

connect(25, {sa_family=AF_INET, sin_port=htons(11211), sin_addr=inet_addr("10.0.41.175")}, 16) = -1 EISCONN (Transport endpoint is already connected)
connect(25, {sa_family=AF_INET, sin_port=htons(11211), sin_addr=inet_addr("10.0.41.175")}, 16) = -1 EISCONN (Transport endpoint is already connected)
connect(25, {sa_family=AF_INET, sin_port=htons(11211), sin_addr=inet_addr("10.0.41.175")}, 16) = -1 EISCONN (Transport endpoint is already connected)
etc.
