That's the reason why this and the related ctime issue were lingering
for so long.

My plan was to pick the low-hanging fruit (the null check) for 3.3 and
leave proper bounds checking and possibly switch to reentrant APIs for
the next release.   There is a long tradition in keeping OS functions'
wrappers thin with an expectation that application programmers will
know the limitations/quirks of their target OSes.  Given that datetime
module does not have these issues, I don't see this as "must fix."
