Comment 15 for bug 1166198

Well, one guy here did get this reproduced on Ubuntu Precise, Python 2.7, and Eventlet 0.12.1 -- though I ran the same and couldn't do it. Either way, if that is working for you it should be safe to run that way just be sure to keep an eye on your /proc/net/sockstat to see if sockets are "leaking". This is a pretty confined area of the code so if it's just a problem with our systems we can remove that crazy code and we can patch it easy enough ourselves, or put in a config switch to turn it on or off in case someone else runs into the same problem we had.
