libssh2 uses only non-blocking sockets internally, and the idea is to remember
the state so that when you stop using libssh2 on the socket it would bring it
back to the previous state. I'm not convinced that's a feature anyone really
cares about.

No, it should make libssh2 work fine, it just can't restore the state to what
it was before.

If this is your only hurdle, then certainly not! We can always add conditional
code to allow even such libs to play libssh2.
