It is a host of corner cases where the CD remained connected and unremoved. This is not a concern with the "real" devices, as they can be present on the system and become unconnected. It could be the same case for a shared CD if we'd have supported such a state. But we decided to disallow it - if the connection is lost, the Cd devices should be gone. This creates a potentially problematic state. Instead of hunting after all such cases and in some cases finding it difficult to cope with them, it seems to be reasonable to solve it this way. We may decide otherwise, but I'd suggest that even then we accept the patch, leave it as a known issue and dedicate a few separate patches to the fix, perhaps immediately.
