Can you explain what this patch does a bit? The way I see it, it's just adding an extra level of indirection to each cur_thread() call. Is that it? Does that affect the performance of TSan?
Can we have some tests added that show what exactly can TSan now achieve with fibers?
If the approach gets approved by @dvyukov, I'd like to make sure that the work can be re-used to implement proper understanding of Darwin GCD queues.
