    You mean, for example,
    bee13000-bee2c000 rw-s 00000000 00:05 7405782 /SYSVa8020046 (deleted)

    It's not the memory which has been "(deleted)", that's still filling your
    virtual address space. It means that shared memory objects /SYSVxxxxxxxx
    are not really there on your filesystem, and so are displayed as deleted:
    an mmapping of an unlinked file is shown that way.
