I'd sure like to see green dashboards! :)

For our dashboards, all the failing tests are either: 1) filed in the
bug database (4340, 4605) 2) failing on many machines or 3) the special
case: there are some tests that fail only intermittently. Like today:

<http://www.vtk.org/Testing/Sites/RogueResearchi386/MacOSXTiger-i386-
cocoa/20070404-0300-Nightly/Results/_
_Imaging_Testing_Tcl_TestAnisotropicDiffusion3D-image.html>

We have looked into this a little bit, and I believe it's the same root
problem for each of the tests that fail intermittently.  It seems to be
a threading bug of some kind.  I must run the test about 30 times before
it fails once.  The result is always a crash very much like below. 
Anyone seen this elsewhere?
