That's a really good point from Aaron... especially if your machine serves 
with Samba, smbd can still have a finger on apparently dead files.  lsof -n | 
grep smbd will show them if that is the case, and service smb restart will 
magically free the 'deleted' files.  I had that here with some large media 
files I had served over Samba, then deleted at the server, but I was not 
getting my space back due to smbd feeling nostalgic for them.
