#49 Processor affinity & #19 Dynamic sample size - both disabled

Processor affinity, whilst useful for diagnostics, has a moderate performance penalty if all CPU-intensive threads are bound and a small (<5% and within sampling error) penalty if just the tree search thread is bound.

Dynamic sample size is absolutely all over the place.
