Hans,

That is a great idea.  However, can I be sure the file is completely
written to disk before tar prints the filename?

You will tell us.

Write a script which handle the job. Let it start like this:
#!/bin/bash
S1=$( stat -c %s $1 )
sleep 1
S2=$( stat -c %s $1 )
if [ $S1 != $S2 ]; then
  echo "Error, race condition. File not written. $S1 $S2"
  exit 1
fi
