Comment (by simonpj):

 * Investigate carefully before trusting the nofib runtimes.  They can
 wobble around a lot; you really need criterion and nofib doesn't use that.
 eg It's very unusual to see a genuine 9% increase in runtime with zero
 change in allocation on a program that is not spending a lot of time in
 non-allocating numeric loops.

 * Why is allocation going up?  That's unexpected.

 * The fibheaps binary size is also a surprise.  12% is a lot.
