patch applied - this will be in openssh-6.0. Thanks!

A workaround for versions before 6.0: instead of

    ssh -W %h:%p gateway

Use:

    sh -c "ssh gateway true < /dev/null && ssh -W %h:%p gateway"

The first ssh call does not use -W so it is not affected by this bug.
It makes sure that the master process is running. The second call does
not need to fork a master so it is not affected either.
