Try adding a call to *set_timeout() just before we call
libssh2_session_disconnect() to instruct libssh2 to give up the waiting after
2 seconds. Like this:

diff --git a/lib/ssh.c b/lib/ssh.c
index 8c68adcc1..a5f69ac08 100644
--- a/lib/ssh.c
+++ b/lib/ssh.c

*conn, bool *block)
          }
          sshc->ssh_channel = NULL;
        }

        if(sshc->ssh_session) {
+ libssh2_session_set_timeout(sshc->ssh_session, 2L);
          rc = libssh2_session_disconnect(sshc->ssh_session, "Shutdown");
          if(rc == LIBSSH2_ERROR_EAGAIN) {
            break;
          }
          if(rc < 0) {
