Comment (by simonpj):

 There's a little-known file `nofib/Simon-nofib-notes` that contains per-
 benchmark commentary.  Could you add the info above to it?

 The notes concentrate on aspects of nofib that have proved fragile, and
 are supposed to stop you reinventing the wheel when you are investigating
 a nofib perf blip.

 Thanks

 Simon
