1. You can't assume that errno starts out zero, unless you zero it
right before SSL_connect.
2. I wonder whether it's safe to assume that errno (a/k/a SOCK_ERRNO)
can't be clobbered by SSL_get_verify_result.
3. It seems weird to refer to errno directly just a couple lines away
from where we refer to it via SOCK_ERRNO. Will this even compile
on Windows?
