Tango-internal unit tests crash on Macs. The offending module for this crash has its unit tests fail. This bug has been reported to the Tango team. I hope it gets fixed soon.

Changed title for greater accuracy (based on current understanding of problem)

Depends on http://www.dsource.org/projects/tango/ticket/1112
