Comment 9 for bug 1311804

This bug should not have been closed for neutron. The performance argument is weak because this code is only called during interface creation. The trade-off for a tiny bit of performance in infrequent code for neutron completely breaking in some environments is unacceptable IMO. This already wasted an afternoon on my part any I'm relatively familiar with the neutron code. This would be nearly impossible to debug for a deployer.
