Good to know! I will rework assuming that the memory is 4, let me
know if you learn more.

This new information will likely reduce the predicted probability of
bluescreen by several orders of magnitude for large directories. Not
that much effect for small directories, but not a real issue given
how low the probabilities are to begin with.

Well, let's see if I can produce a reasonably realistic model. :-)
