Description

I can cause the dispatcher to crash by having two Messenger clients subscribe to the same address, with non-zero outgoing window sizes.

To reproduce:

1) Run ./router/dispatch-router -c ../etc/qpid-dispatch.conf
2) Start two msgr-recv clients like this:

msgr-recv -a amqp://0.0.0.0/test.topic -W 2048 -R &
msgr-recv -a amqp://0.0.0.0/test.topic -W 2048 -R &

3) Run a msgr-send client like this:

msgr-send -c 1 -w 2048 -a amqp://0.0.0.0/test.topic -R

This should cause dispatch-router to crash.
