It's reasonable for a file system to reorganize itself while 'tar' is 
reading files. Even if a file's contents do not change, its space 
utilization might change. When I use "du" or "df" to find out about 
space utilization I want the numbers now, not what they were last week, 
and this is true regardless of whether I have modified the files since 
last week.

Sorry, didn't read the other email. Let's keep that water under the 
bridge. Fighting fire with fire is not the best way forward here.
