JH/12 Fix an uninitialised flag in early-pipelining. Previously connections
could, depending on the platform, hang at the STARTTLS response.
+JH/13 Bug 2498: Reset a counter used for ARC verify before handling another
+ message on a connection. Previously if one message had ARC headers and
+ the following one did not, a crash could result when adding an
+ Authentication-Results: header.
+
+JH/14 On GNU/Hurd, retry EINTR returns from I/O on pipes, which seem to occur
+ frequently.
