1) It would appear that the cpuaffinity setting only works on
windoze (as documented) - that is a bloody shame as a 2 cpu Unix or
Linux machine could benefit here a lot

2) the SS goes to 99% cpu utilization (and sometimes core dumps)
when extreme cleanup and housekeeping is required by a transaction.
It's memory utilization goes up and up (ok if enough swap space, core
dump if not) - the lack of real memory may be the real reason for the
high cpu utilization - it may be swapping like heck.
