Hi,

I am having some race condition issues on my server when trying to 
delete a file.

//
function my_unlink( $filename )
{
   //  remove the old file
   clearstatcache(TRUE, $filename);
   if (file_exists($filename))
   {
     @unlink($filename);
   }
   else
   {
     return true;
   }

   clearstatcache(TRUE, $filename);
   return (!file_exists($filename));  // check it was deleted.
}
//

In some cases I get

unlink(/home/xxx/public_html/temp/yyy.zz) [function.unlink]: No such 
file or directory

How can I prevent the warning?

Thanks

Simon
