This doesn't sound quite right. The only safe way is to CREATE the 
file in 600 mode right away. If you just CHANGE to 600 even before writing 
to it, there IS an unsafe window.
Try the following:
touch x
tail -f x

Then in another shell:
chmod -r x
echo bla >> x

"bla" will show up in the first window, read by "tail".

Kind regards,
