I think it makes sense to do this ASAP.
I tried and had some issues with it.
Are there specific commits I could cherry pick,
or will I wait for essex-4 which is supposed
to land on March 1st, 7 days before the test day.

I'm not sure of the implications. It seems dafe enough.
If the option is just to cater for systems without `dhcp_release`
then it's fairly redundant, as the availability of that could be
checked for at startup. Not that it would be the first redundant
option ever created :)  I'll ask on the openstack list.

I ran through most of the test day cases with no issue.

I discussed that with Russell who implemented the Qpid support,
and he made the point that you might not even want to run the
qpid broker on the same host as the nova services.
I intentionally didn't depend on an amqp server for now.
