I am of the opinion, that context switch time has nothing to do with multithreaded applications (at least on Solaris) because a multithreaded application is always in the same "context" (because of shared global address space of such a program).
There is more to "context" than just the address space id. For example, to switch between threads of the same process we still have to preserve registers etc of the outgoing thread and restore those of the incoming thread ready for execution; true we do not have to reprogram the context registers if the threads are of the same process, but that is just one part of the overall resume() operation.
