Instead of closing the file handle, you could just release the lock.  flock $fh, LOCK_UN or die "flock can't release lock $!";

Note from the docs: "To avoid the possibility of miscoordination, Perl now flushes FILEHANDLE before locking or unlocking it."
So, lock, write, unlock will cause 2 flushes. There is no need to explicitly seek or flush.
