Doesn't sound familiar, I've never had this problem. However, the TLS code was
refactored in rev 2.4.14, and it's always possible we missed something in the
churn. How does openssl s_client react under the same conditions? If it hangs
the same way, then that points to a bug on the server, and the answer is just
to upgrade since .12 is rather out of date now. If s_client works, then we
probably have to look at our client code.
