I find this a little bit optimistic.  For one, my empirical tests gave
read errors when 4700000000 or more were written.  Thus length should
be no more than 4450 when isofs-overhead is regarded.

Besides this, in the last couple of weeks I experience something 4GB
related.  I have started a thread on

  http://lists.suse.com/archive/suse-linux-e/2006-Apr/0334.html

but no result so far. :-(

So I reduced the length to 4000mb
