The implemented cloning mechanism should be sound: - If a PartitionTable is passed a File with ShouldCloseFileDescriptor::Yes, then it will keep it alive until the PartitionTable is destroyed. - If a PartitionTable is passed a File with ShouldCloseFileDescriptor::No, then the caller has to ensure that the file descriptor remains alive. If the caller is EBRPartitionTable, the same consideration holds. If the caller is PartitionEditor::PartitionModel, this is satisfied by keeping an OwnPtr<Core::File> around which is the originally opened file. Therefore, we never leak any fds, and never access a Core::File or fd after destroying it.
