Anton Shmigirilov commented on ARROW-2359:
------------------------------------------
It seems original topic message is incorrect. It looks like there aren't races
in singleton itself. There is another race condition in my code somewhere, it's
related to arrow::DataType usages and it's eliminated if singleton is removed
using proposed patch. Anyway, this JIRA task has wrong description and can be
removed or renamed, if needed. Guys, sorry for confuse. (But I still think that
static shared_ptr is over-engineering ;) )

> TYPE_FACTORY() macro that produces type shortcuts (boolean(), int32(), utf8()
> and so on) uses static shared_ptr inside. There are race conditions possible
> against shared_ptr's reference counter.
