Currently, no tests would fail if we were to apply this optimisation to getattr_static, which makes things a fair bit faster:

--- a/Lib/inspect.py
+++ b/Lib/inspect.py
@@ -1780,13 +1780,9 @@ def trace(context=1):


 def _check_instance(obj, attr):
-    instance_dict = {}
-    try:
-        instance_dict = object.__getattribute__(obj, "__dict__")
-    except AttributeError:
-        pass
-    return dict.get(instance_dict, attr, _sentinel)
-
+    if hasattr(obj, "__dict__"):
+        return dict.get(obj.__dict__, attr, _sentinel)
+    return _sentinel

However, the optimisation would lead to incorrect behaviour. test_custom___getattribute__, added in this PR, would correctly fail if the incorrect optimisation were applied.

Sorry @AlexWaygood, I had trouble checking out the 3.11 backport branch.
Please retry by removing and re-adding the "needs backport to 3.11" label.
Alternatively, you can backport using cherry_picker on the command line.
