Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections.

PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency.
r4648@asus: jeremy | 2006-06-19 13:08:40 -0700
Pass the default allow_concurrency when instantiating new connections.
r4649@asus: jeremy | 2006-06-19 13:11:12 -0700
Break out concurrent transaction tests and run them for PostgreSQLAdapter only (need to fork or system('some_test_script') for the other adapters)

Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE".
