For non-OSGi dependencies undeploy is the correct behavior. It is the 
only way to get anything close to consistent behavior.

For now I will re-work my patch so that the deployment only restarts if 
the re-deployment is a result of an inter-deployment dependency, rather 
than an OSGi deferred resolve.
