Prevent deadlocks when waiting for connection from pool.
When a thread that had the load interlock but was blocked waiting to check a connection out of the connection pool but all of the threads using the available connections were blocked waiting to obtain the load interlock an `ActiveRecord::ConnectionTimeoutError` exception was be thrown by the thread waiting for the connection.
When waiting for the connection to check out we should allow loading to proceed to avoid this deadlock.
