Another thought: isn't it racy for even worker threads?
I a thread
Acreates a task for threadB, doesn'tSpanget linked toAs spans stack?
We were creating a span, attaching it to the coro stack to immediately detach it. After that we were passing it to another thread and attaching to its coro stak.
With the patch we do not do unnecessary attach+detach, Span just starts detached. As a result, it may even speedup some workload. Attaching to stack is implemented via task local variables, which may do two memory allocation in worst case
