Unison is rather paranoid about doing anything to your filesystems:  
at the very last moment -- just before doing the deletion in this  
case -- it re-fingerprints the file to make completely sure it has  
not changed.

If you don't mind recompiling from source, it would be easy to remove  
this check.

Regards,

     - Benjamin

&gt; I've noticed that files that have been deleted take a very long  <br>
