Yes.

We switch back to blocking sockets again, after the connect is done. We
should probably consider not doing that switch back...

Uh. Not right now (need to study related OpenSSL stuff first). Can you make
sure that this is really the case?

Using signals is not a good solution. Using non-blocking sockets might be
better, as then OpenSSL shouldn't be able to hang either.
