Reiser fill system filled, deleted the files and its still full

[hanasaki <hanasaki@hanaden.com>]

A Reiser filesystem, under sarge, was accidently filled.  The files were 
removed but the space was not released.  How can this be?  How can it be 
fixed?

I tried running reiserfsc but it cant work on a mounted partition.  I 
only have one partition.
