+# OpenSSL client will always try an abbreviated handshake (i.e. it will supply
+# the session id). This goes all the way to commit 48ae85b6f when abbreviated
+# handshake support was first added. Neither behaviour is wrong, but the
+# discrepancy is strange. TODO: Should we harmonise the TLS and DTLS behaviour,
