[Insight-developers] itkMattesMutualInformationImageToImageMetricTest failures

[Luis Ibanez]

Hi Bill,

I'll do the runs with a single thread (I haven't done that yet).   :-/


I was following the problems reported by valgrind, and I think
I fix them this time. However, the valgrind builds are using
the non-multi-threaded classes. (so there is still room for
errors in the multi-threaded ones.).
