That's something I haven't seen. But then, I don't usually see the
client side; I just see the fallback dumb fetch in our logs, and
have occasionally followed up.

Is there a long pause while the user is typing their password?

You could try turning off CURLOPT_SSL_SESSIONID_CACHE and seeing if that
improves it. Of course, it is probably hard to reproduce, so it would be
tough to know if that helped or not. It would also be nice if you could
dump more information on the error from the ssl library (I typically
build curl against openssl; I wonder if it could be related to using
gnutls or something).
