It appears that glibc 2.13 has the same thread descriptor size as 2.11,
bump up the inflection point to 2.14. If someone can tell me how to
actually figure out value for this, that would be awesome.

Anyways, this takes me to one ASan failure, one LSan failure, and three
TSan failures for 'check-all' on Linux.
