Yeah, at least partly.  That and the fact that I'm not too willing to
dig into the code without further evidence.  It isn't anything strange
to ask tho and I'm likely to do that even for subsystems that I know
intimately if the subject code has been stable / stale for years and
the analysis doesn't seem immediately convincing.  And, if my
experience is anything to go by, it's not too unlikely that you might
hit something which doesn't agree with your current assumptions while
trying to actually trigger the problem.

Thanks.
