Comment(by simonmar):

 Perhaps you should check that the scheduling behaviour is the same. e.g.
 in sieve, if we manage to run a thread to completion in one time slice,
 then it won't need to be copied by the GC, but if it gets preempted then
 it will get copied.

 A glance at the ThreadScope profile, or even just the eventlog, might be
 illuminating.  Also check the `+RTS -s` stats, a good sanity check is
 whether the amount of allocation is the same (if not, something strange is
 going on).  And the GC stats will give you more clues.
