Consider Adding Thread Affinity

[Suminda Sirinath Salpitikorala Dharmasena]

This mainly aims to prevent cache misses as:
- previously cached values of the thread may be in the cache
- threads which share data can be targeted at a given core for better data
locality
- ensure threads are planned based on locks are common/shared
resource usage which is known to the programmer than OS

I believe this is an important feature to consider for performance.
