This is roughly what was happening.  A bit later this week, I'm going
to sit down and really examine this problem.  I was doing something
like this:

(note that this code is from memory.  I'm not sure if this will run
correctly or if it will reproduce my problem)

class TestRequest < RUNIT::TestCase
    def teardown
        if (defined? MOD_RUBY)
            Object.module_eval{ remove_const :MOD_RUBY }
        end
    end

    def test_parse_with_mod_ruby
        Object.const_set( :MOD_RUBY, true )
        assert( defined? MOD_RUBY )       # <= this was true
        assert( CGI::Request.mod_ruby? )  # <= this was false?
    end
end

class CGI
    class Request
        def Request.mod_ruby?
            defined? MOD_RUBY
        end
    end
end

By the end of this week, I'm going to sit down and examine this
problem further.  Then I will double check my code, and try to get a
clear demonstration of my problem.

Thanks,

Patrick
