We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.
