There are a lot of reasons why there might be generation failures. I mean, basically, it is a randomized solver that is going off and searching for solutions and sometimes...

Oh, and if someone actually wants to get dirty working with the solver, I believe that @bfetscher built something to visualize the steps that the solver takes so you can...

How about using `build-derivations`? As for the "try to make as big a derivation as you can", I've long thought that would be nice to have, but it isn't a...
