If you find there is 1:1 threading mode Jeff added in kernel,
I bet you will understand why I need to change it to P_SA.
why shouldn't 1:1 code be called as P_THREADED ? I think this
flags is confusing. P_SA tells you that the threading mode
a process is using is Scheduler Activation based --- Anderson's
theory.
