I can see a few of problems:
* If more than one thread calls get_data() during the initial
cache filling, it looks like only one of them will wait for
the thread -- the others will skip waiting altogether and
immediately return None.
* Also if the first call to get_data() times out it will
return None (although maybe that's acceptable if the caller
is expecting it).
* The caller of get_data() is getting an object that could
be changed under it by a future update.
