You should continue using select() then. gnutls_check_pending() checks
for data in the gnutls_session_t buffers, not in the network buffers.
You should use it to complement select() (i.e., call select() if
gnutls_record_check_pending() returned zero).
This is what gnutls-cli does.

You don't need it. Use select() instead.

If your socket is set to block it will block.
