:> procfs        4.0K   4.0K     0B   100%    /proc
:> www            19G   8.0M    19G     0%    /www
:> the 8M space is not released.
:HAMMER internally uses 8M blocks, so df will always show multiples
:of 8M for used space.
:However, if you create more files in /www, df used count should
:stay at 8M until your files use up more than these 8M, at
:which point it will probabely switch to 16M.

    Yah, that's basically correct.  HAMMER uses different zones for different
    kinds of allocations as well, so upwards of 40MB may be marked allocated
    even if the filesystem appears empty.
