I'm happy to do it, but I'm not sure when I'll be able to find an
uninterrupted period of time which it requires.

So I suggest that if you have other development tasks to do, then do 
those, otherwise feel free to rewrite covariance matrix yourself.

I'm not adverse to using hash tables in covariance matrix if they are 
needed, but I don't think they are necessary for the simple case (without
interactions/categorical variables).

     I ask because I was the one who wrote all the crap in
     covariance-matrix.c in the first place, so on one hand, I kind of feel
     responsible, but on the other, writing crap doesn't exactly enhance
     one's confidence or motivation.
