That service code is actually from the Oslo incubator, so we should fix
it there. If we can always call engine.dispose(), then let's put that
into the incubated module and see how it works in cinder (submit the
patch to the incubator, then update cinder's copy and submit a patch
with Depends-On set to point to the patch to the incubator so the copy
in cinder won't be updated until we land the fix in the incubator).
