just a side note:
/dev/full seems to be broken on some (old?) kernels:

  $ ls -l /dev/full
  crw--w--w- 1 root root 1, 7 2009-08-17 09:55 /dev/full
  $ uname -a
  Linux linx2 2.6.16.60-0.23-smp #1 SMP Thu May 15 06:38:31 UTC 2008 i686 i686 
i386
  $ echo "Hello world" > /dev/full
  $

This was on "SUSE Linux Enterprise Server 10" while the
test works on another box with 2.6.24.4 (knoppix 5.3.1).
Maybe the test on /dev/full should be enhanced ...
