Subject: Do not log errors when recvfrom() returns EAGAIN or EINTR.
X-Git-Tag: release-1.0.10~50

Do not log errors when recvfrom() returns EAGAIN or EINTR.

Although we select() before we call recvfrom(), it sometimes happens that
select() tells us we can read but a subsequent read fails anyway. This is
harmless.
