A small experiment. Run this from one terminal (sorry for the long
line):

$ perl -e 'select(STDOUT); $|=1; for (0..1000000) { print 1; sleep 1 && system("ls -l t.gz >> t") unless $_ % 200000; }' | gzip - > t.gz

And watch content of file t with tail -f from another. (You may need
to remove a couple of zeros above, my machine is very fast:) This is
what I see:

$ tail -f t
-rw-rw-r--    1 vik      vik             0 Sep  8 10:51 t.gz
-rw-rw-r--    1 vik      vik             0 Sep  8 10:51 t.gz
-rw-rw-r--    1 vik      vik             0 Sep  8 10:51 t.gz

Any ideas why?
