Keep a reference on objects to preserve their content.
Modify tmpfs to keep a reference (by mapping it into its
own space) to each memory object created by the user, so they don't get
inmediately terminated at the end of the current operation.
* tmpfs/tmpfs.h (struct disknode): Add `memref' field.
* tmpfs/node.c (diskfs_get_filemap): vm_map() the first page of the
newly-allocated object, store in `memref' field.
(diskfs_free_node) vm_deallocate the page pointed by `memref' field.
