Comment (by tscrim):

 Took 3.5Gb of RAM with this ticket, but on my laptop, this is what I got:
 {{{
 sage: W = ReflectionGroup(['E',8])
 sage: from sage.combinat.root_system.reflection_group_c import
 parabolic_iteration
 sage: %time for w in parabolic_iteration(W): pass
 CPU times: user 4min 23s, sys: 604 ms, total: 4min 23s
 Wall time: 4min 23s
 }}}
