I'm using contrib/test_summary and haven't seen any non-determinisms in the
output of that command. As for dg-extract-results.sh, we have two versions
of that, one if you have python 2.6 or newer, another one if you don't.
Perhaps the behavior of those two (I'm using the python version probably)
differs?
