       queue_run_in_order means we cannot do this, as ordering becomes
       indeterminate.
 
+JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage.  A previous fix
+      had introduced a string-copy (for ensuring NUL-termination) which was not
+      appropriate for that case, which can include embedded NUL bytes in the
+      block of data.  Investigation showed the copy to actually be needless, the
+      data being length-specified.
+
+JH/25 Fix use of concurrent TLS connections under GnuTLS.  When a callout was
+      done during a receiving connection, and both used TLS, global info was
+      used rather than per-connection info for tracking the state of data
+      queued for transmission.  This could result in a connection hang.
