Nope, that's why there is RT-NPTL. And that library is still in flux, especially now with the ongoing work on PREEMPT_RT. Let's wait for the result and see if it is feasible to reuse this userspace infrastructure. For now, I'm convinced that it is much more comfortable for the user to obtain kernel extension and userspace library from one hand with a clear and consistent versioning. Jan
