In release 1 some frameworks refreshed "eagerly", restarting any 
dependent bundles, other frameworks left the packages lying around and
resolved the problem lazy. In release 2 we mandate the lazy approach but 
provide a special service, the PackageAdmin service that allows the 
Management Agent to initiate a refresh (and expose the current status of 
package sharing). The refresh can do a global refresh or for a set of 
bundles.

The idea behind this is that a management agent can install several 
bundles before it refreshes saving time and some error scenarios.

BTW, what stayed around were exported packages not the bundle.

Kind regards,
