but it's slower (on SMP) and more error-prone to use threads. We have the following task: 'use multiple contexts and share some state'. The 'share everything' model overdoes this goal a bit. Why not share the *specific* state that should be shared, and nothing more? The fact that this is inconsistent across platforms is IMHO not a good excuse - it just shows the mistaken concept that threads should be used for such tasks. You are right about the semaphore part - i have plans to add a new type of semaphore to Linux, which are not as complex as SysV semaphores and are not persistent.
