Comment (by knarf):

 Moving the release target again is unfortunate, I agree. It is not
 critical, however. The release tag should only indicate that this "should
 be fixed by that release".

 It would be nice if issues with the test system would get more attention
 though. I would think they should be critical. The past showed that while
 most probably agree with that statement, reality tells differently. As for
 the next release: I don't think whatever solution we might come up with
 would make it in the release. There isn't enough time for it. I still
 think this is important enough to keep reminding ourselves.

 On this specific issue: the underlying root issue is that most testsuites
 that set a specific number of processes run just fine on other numbers,
 but their output can currently not be successfully compared by Cactus.
 This could be fixed by either Cactus being able to compare the files, or
 by having processor-number-independend output files. The former was
 started by a student at LSU, but died after the student decided to stop
 working on it (undergraduate...). The latter would be nice, but didn't
 happen so far and especially performance implications are unclear. So, in
 order to pick up one or the other again in the future we should keep this
 ticket open - and it is important enough to keep reminding us about this
 embarrassing issue.
