+Subject: [PATCH] Fix intermittent failures in missing client private key test
+
+Because our APIs do nice things like encapsulating the TLS connection
+establishment, we have our test server writing to the client after
+establishing the TCP connection, because the TLS connection is
+established. It's fine in theory, but results in some weirdness like the
+server seeing its write having completed successfully before TLS
+connection establishment. Normally that's what happens and this test
+passes (server sees no error), but sometimes the server sees that the
+client has already failed and the test fails.
+
+This is unfortunate, and tricky to fix properly, so let's just remove
+the bad check. The point of the test is to ensure that the TLS
+connection is not established, and the client-side check is going to
+have to be sufficient, because rewriting the test to wait for the TLS
+connection to be established on the server side is quite tricky: my
+naive attempt resulted in both sides waiting forever on the other.
+
+P.S. At no point in this test does the server ever examine the client
+certificate. That's not quite what I expected when I added the test, but
+it's fine.
+
+Fixes #4
