  -----------
  login-proxy: Fixed assert-crash/hang on connect errors.

The internal BUG would have left the host hanging. "Host is down" or any
immediate connect() error would have assert-crashed with:

Panic: file login-proxy.c: line 470 (login_proxy_disconnect): assertion failed: (proxy->state_rec->num_waiting_connections > 0)
