Hohum, this is probably because I forgot to close() the file in the
read() part of the test... *blush*

I just reran the test on my laptop (arthur: Celeron (Coppermine) 500,
128MB, SuSE 7.0 + updates, linux-2.4.2, gcc-2.95.2) and got "only" 963
errors. I also ran the test om my desktop (zaphod: AMD K6-3D/333,
160MB, Debian 2.2 + updates, linux-2.4.2-pre4+reiserfs patch,
gcc-2.95.2) and got 888 errors.

An interesting observation is that the two systems have the bugs in
almost the same places. Attached is a diff between the output files of
both systems.
