Hi Corinna,
I have the impression that 20111124 is working better than 20111129,
and that 20111204 and 05 have some additional problems.

On 20111129, building atlas on W7/x64 I see the custom config spinning 
and never ending, while on 20111124 is goes smooth.

On 20111204 and 05, I see forking problems on octave with
some puzzling message about fifo issues. Rebaseall is ineffective.

I will look to build some simple test case for both problems.

Regards
Marco
