This line of thought is cold comfort to me.  In my opinion, the recent Linux
backdoor insertion would have worked if the attacker had inserted it into
a developer's actual patch instead of inserting it into the CVS tree.

My point is that the backdoor was sufficiently innocuous looking and
sufficiently small that it probably would not have been discovered during
casual code-reading, nor would it probably have caused merge conflicts or other
problems that would draw attention to it.

Unfortunately, I can't think of a solution to this problem in the context of
darcs.  I guess for now I'll just have to accept this risk as the price of
using darcs.
