I think the problem stems largely from the ActiveRecord connection adapter
API.  It provides no mechanism for acquiring or releasing table level locks.

If you could get a table level lock, then checking the uniqueness of a value
before performing an insert/update could be an atomic, as well as performing
a find_or_create_by type operation
