Has the changes that have gone into the check parallelization made

I'm seeing a lot of small hunks in different orders which cause my
comparison scripts to show big differences.
I haven't been paying attention to the nature of the make check
changes so
Im not sure if this is expected...

Or is this something else?  Its the same code base between runs,
just with a
few changes made to some include files.
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?

Not sure, although I do have python 2.7.5 installed for what its
worth...  I'll try another run in a bit.

Andrew

hum. My 3rd run (which has no compilation change from the 2nd one) is
different from both other runs  :-P.   I did tweak my -j parameter in
the make check, but that is it.

I'm also seeing this. Python 3.3.5 here.
