Yeah, that's pretty much the approach libpq has taken: write (or read)
when you can, but press on when you can't.

We have not had word of any such problem with libpq. It's possible that
the intersection of SSL users with non-blocking-mode users is nil, but
I kinda doubt that. You do need to interpret openssl's return codes
correctly ...
