+#
+#   cdef class OurUUID:
+#       ...
+#
+#   class UUID(OurUUID, uuid.UUID):
+#       ...
+#
+# With Python 3.8 it now produces
+#
+#   "TypeError: multiple bases have instance lay-out conflict"
+#
+# error.  Maybe it's possible to fix this some other way, but
+# the best solution possible would be to just contribute our
+# faster UUID to the standard library and not have this problem
+# at all.  For now this hack is pretty safe and should be
+# compatible with future Pythons for long enough.
