We ARE stat'ing and perl'ing... but actually we do not (yet) have a 
performance issue and I haven't benchmarked it...

FWIW:
# after I have written my message (with all the router envelope)
# to "$some_tmp_dir/$msgfile" and closed it, I do the following:

my ($dev,$inode,$mode,$nlink,$uid,$gid,$rdev,$size,
   $atime,$mtime,$ctime,$blksize,$blocks) = stat("$some_tmp_dir/$msgfile");
rename "$newrouter_dir/$file", "$router_dir/$inode";

perl is itoa'ing for you :-)
