title: "lsof" shows a file as (deleted) but I can still see it in file system
body: <p>in Linux 2.6.27:</p>
  
  <p>From "lsof" output I see a process holding open fd with a (deleted) file. The strange thing is that I can still see the file in the file system using "ls".  Why is that? </p>
  
  <p>thanks.</p>
