#commit b406b87
# BUG/MEDIUM: connection: don't store recv() result into trash.data
#
# Cyril Bonté discovered that the proxy protocol randomly fails since
# commit 843b7cb ("MEDIUM: chunks: make the chunk struct's fields match
# the buffer struct"). This is because we used to store recv()'s return
# code into trash.data which is now unsigned, so it never compares as
# negative against 0. Let's clean this up and test the result itself
# without storing it first.
