With the mainline on ppc-darwin we have a huge problem in the scheduler:
scheduling : 131.99 (44%) usr 52.35 (75%) sys 231.63 (46%) wall
PRE (GCSE) is also a problem too:
PRE : 38.78 (13%) usr 1.82 ( 3%) sys 73.43 (15%) wall
For the scheduler at least we have linked lists which we allocate a lot of.
