timestamps will lose precision thanks to time_t < double (bug #919012).
Extension modules
-----------------
+- time module code that deals with time_t timestamps will now raise a
+ ValueError if more than a second is lost in precision from time_t being less
+ precise than a double. Closes bug #919012.

- fcntl.ioctl now warns if the mutate flag is not specified.
- nt now properly allows to refer to UNC roots, e.g. in nt.stat().
