You are writing the file to one file system and then "renaming" it to a different file system?
My mistake! Of course the file will always be on the same file system.

You haven't even bothered to read any Unix man pages for rename?
I think this doesn't help much here, because this would cover only the case where my process runs on Unix. If at least one of the processes runs on Windows (which might be Windows 2000, XP or Windows 7), the explanations in the Unix man page don't help. What is important here is how Perl implements 'rename' - and yes, I did read the Perldocs for rename, and also the section in 'perlport'.
