gh-91048: Prevent optimizing away the asyncio debug offsets structure on Windows ( #132963 )
...
To avoid having the debug sections being optimised away by the compiler
we use __attribute__((used)) on gcc and clang but in Windows this is
not supported by the Microsoft compiler and there is no equivalent flag.
Unfortunately Windows offers almost no alternative other than exporting
the symbol in the dynamic table or using it somehow.

gh-129898: per-thread current task implementation in asyncio ( #129899 )
...
Store the current running task on the thread state, it makes it thread safe for the free-threading build and while improving performance as there is no lock contention, this effectively makes it lock free.
When accessing the current task of the current running loop in current thread, no locking is required and can be acessed without locking.
In the rare case of accessing current task of a loop running in a different thread, the stop the world pauses is used in free-threading builds to stop all other running threads and find the task for the specified loop.
This also makes it easier for external introspection to find the current task, and now it will be always correct.
