Re:migrating, load-balancing, 2.4.26, 2.4.24, Virtual PC

Hmm .. you might be fighting two problems here.

Your test script looks like a shell script, but I don't
recognise the $((var+i)) operation .. I'm used to
$(( $var + $i )) ...   In the testing I did for the build
paper, I found that my shell script's wouldn't auto-
migrate, which is why I resorted to Perl .. try this out;

#!/usr/bin/perl
$i=1;
while($i) {
  $i++;
}

.. it should auto-migrate .. all things being equal.
