I suppose - but if OpenSSL *just didn't try to do networking*,
we wouldn't have to learn the BIO abstraction. Sure would be
easier. I think this is a case of the library trying to
do too much, and ending up being hard to use.
But I am soldiering on, trying to understand the BIO part.
I'm having trouble using BIO pairs to set up a nonblocking
connection.
