 - The [RFC](https://discourse.llvm.org/t/rfc-tsan-implementing-a-fuzz-scheduler-for-tsan/80969) suggests moving the scheduler to sanitizer_common, so that ASAN can leverage this. This should be done (should it be done in this PR?).

I would say No. I think it's more important to merge this long-standing improvement. This would be very useful on its own. We can keep other sanitizers as TODO. I don't mind if you do that too, but don't feel obligated to.

 - Missing interceptors for libdispatch
 
That's fine. TODO is OK.
