  Ah, I just managed to reproduce this.  That is indeed rather strange.  Hmm.  

  Oh, hang on, it gets more interesting, I just got it to *really* fail.  Here's
a test on a file with 4207 lines in it.....

dk@mace /artimi/firmware> cat diffs.txt  | tee tmp2.txt  | head -4100 > /dev/nu
ll
tee: write error
dk@mace /artimi/firmware> cat diffs.txt  | tee tmp2.txt  | head -4100 > /dev/nu

Terminate batch job (Y/N)?


  Wow.  The last time where I tried it, it paused for a long time as if it had
hung, and then managed to kill my entire bash shell and cygwin.bat session.  I
guess there really is a bug there.

    cheers,
