+Subject: [PATCH] add support for Python 3.7 uuid module changes
+
+Python 3.7 removed uuid._uuid_generate_time. It now has
+uuid._load_system_functions and uuid._generate_time_safe.
+_generate_time_safe is set by calling _load_system_functions (subsequent
+calls to that function are no-op). This change detects the missing
+uuid._uuid_generate_time attribute and uses the new attribute/function
+if they're missing.
