Hmm, it probably makes a latent scheduler issue appear.  Guess for better
analysis we have to trim down the source.  Not sure how - maybe
automatically with one good and one bad rev. looking for a hundred-fold
increase in memory use?  Look at the good compile with /usr/bin/time
and using the RSS to compute a ulimit -v limit or so.
