I agree, too, but as Dave pointed out, my hands are tied at this point. I
think Test::Unit has used (and abused) exit blocks a lot more than was
perhaps ever intended (which, BTW, is Dave's fault in the first place - he
gave me the idea :-). It does seem useful, though, to be able to set the
exit status from an exit block.

For your case, Sean, there is a work around:

  if($0 == __FILE__)
    exit(1) unless(Test::Unit::UI::Console::TestRunner.run(suite).passed?)
  end

Unfortunately, in the current version under 1.8, it requires you to build
the suite yourself. Under the version in /rough/lib/testunit, you could just
do the following:

  exit(1) unless(Test::Unit::AutoRunner::run(__FILE__))

I may get it merged before the 1.8 release; if not, expect it for sure in
1.8.1.
