Relay Egress "Broken Pipe"

[aledcuevas]

Description: In certain situations (not sure exactly when), it seems like the egress server pipe is broken for a particular connection. Sometimes when testing for various bugs, I have found that a connection through a particular socket would become irresponsive while others would work normally. For example, I reached a stated where I would obtain a "Bad Version" error on the public SOCKS proxy and a corresponding "Broken Pipe" on the relay every time I tried to load the english Wikipedia domains. However, connection to other websites (e.g. spanish/italian/german Wikipedia, or other webpages) would work normally.

Steps to reproduce: I haven't found a reliable way to reproduce this issue. Might be related to #204 in some way, though.

Two different sessions where I observed this bug. The two screenshots are not from the same testing session.

It seems that #208 offers an idea on how this issue manifests and how to reproduce it.
