    Hi,

    Freeing the allocated space *is* incredibly slow under Linux though.
    On my machine (P133) it is something like 15 MB/s.

    Tried with HP-UX sometime ago: Not only does the rm command return
    immediatly, but the space is freed also immediatly (as shown by
    "df").

    Greetings,
    Rob van Nieuwkerk
