You are not understanding hyper-threading.  You have two physical
processors, and each is divided into two logical processors, giving you
what _appears_ to be 4 cpus.  When you run two threads, how do you
guarantee that each thread runs on a different physical CPU?  Answer:
You can't.  So you might get both threads on one physical processor
or one on each physical processor, or they might bounce between the
two states.

The moral:

don't _ever_ run two threads on a SMT-enabled dual.  3 is fine, as obviously
two will be on one physical processor and one will be on the other.  Four is
fine.  But _not_ two.

As operating systems become aware of this, they will fix it.  There are linux
patches that solve this, for example.  I don't know about windows.
