I was evaluating some SSL failures, and noticed that when I use
curl to one of the failing sites, I got
curl: (56) SSL read: errno -5961; however, my google queries for that error didn't show the reason for the openssl failure.
What does it mean when curl fails with
curl: (56) SSL read: errno -5961?
I'm including the complete

I am answering my own question, in hopes of helping future googlers.
