Wow.  This is rather strange.  I have to say that my machine at home was
unable to run NUnit after the first time (I do not know what happened
there) so I could not do more testing at that point, I had to write a
small wrapper and write the tests outside NUnit.

I am not sure why NUnit would be catching those errors itself, it does
not seem right.

On the other hand, I have another problem right now: we are shipping
binaries for NUnit and Nant, and they do not work right with the Release
Candidate 0 (I have machines running with RC0 and Beta2), I think we
should include the source code for Nant and Nunit with the package to
avoid this problem, it would also be helpful to track the problems like
this one down.  What do you think?
