Thanks for the advice, but doesn't File::MkTemp have a race condition? 
The subroutine File::MkTemp::mktemp does following (comments are mine):

   $keepgen = 1;

   while ($keepgen){
 
         # generate a random file name and put it into $template

         if ($dir){
            $lookup = File::Spec->catfile($dir, $template);
            $keepgen = 0 unless (-e $lookup); # isn't it a race?
         }else{
            $keepgen = 0;        # here it doesn't even check -e
         }
   
         next if $keepgen == 0;       # also, why this check?
   }
   return($template);

This looks as a bad quality module to me or am I awfully wrong?
