Thanks -- I thought 'urlwrite' allowed you to write data to some given  
url (i.e. save data on some server), but I was mistaken. I do think  
there's a problem with the changes you made. If a file is downloaded  
from some url, it looks like it won't be deleted when we're done with  
it. I mean, shouldn't there be an

   if (file_was_downloaded)
     unlink (fn)
   endif

at the end of the function?
