Rails 3 and rspec 2 turning off transactional fixtures per test

[Dobai-Pataky_BSSSSl]

I am having trouble turning off transactional fixtures per test in
Rails 3 with rspec 2. I did this successfully with rspec 1.3.1 and
rails 2.

rspec version is 2.0.0.rc

Below is my stack overflow question which provides more details:

Rails 3 and Rspec 2 turn off transactional fixtures for individual tests

Any help is appreciated. Thanks!
