Sam Gross	520cf2170e	gh-117688: Fix deadlock in test_no_stale_references with GIL disabled (#117720) ... Check `my_object_collected.wait()` in a loop to give the main thread a chance to merge the reference count fields. Additionally, call `my_object_collected.set()` in a background thread to avoid deadlocking when the destructor is called asynchronously via the eval breaker within the body of of `my_object_collected.wait()`.	2024-04-15 12:54:56 -04:00
Sam Gross	a3af3cb4f4	gh-110481: Implement inter-thread queue for biased reference counting (#114824) ... Biased reference counting maintains two refcount fields in each object: `ob_ref_local` and `ob_ref_shared`. The true refcount is the sum of these two fields. In some cases, when refcounting operations are split across threads, the ob_ref_shared field can be negative (although the total refcount must be at least zero). In this case, the thread that decremented the refcount requests that the owning thread give up ownership and merge the refcount fields.	2024-02-09 17:08:32 -05:00
