Changed default number of threads to 1 instead of autoconfigured value and added a new `auto` variable which enables autoconfiguration of thread count. The number of threads used when autoconfiguratio fails was changed from 4 to 1. The default value of using N threads where N is the number of CPU cores was not optimal as the possibility of rescheduling was higher the more utility threads there were. Due to this, N-1 is deemed to be the better autoconfigured value for thread count.
