before_validation callback affected by rollback if validation failed

When I tryed to do some actions that interact with database in before_validation callback - they were rollback if validation failed.

Simple code to demonstrate examle:

class Message < ActiveRecord::Base
end

class PersistentCallbackDeveloper < ActiveRecord::Base

  set_table_name 'developers'

  validates_presence_of :name

  before_validation do 
    Message.create!(:body => "Validating #{self.inspect}")
  end

end

And the test:

def test_persistent_callbacks
  assert !PersistentCallbackDeveloper.create
  assert Message.exists?
end

The second assertion fail.

I think this is not correct: before and after validation callbacks should not be a part of transaction around save.

What do you think?

Thanks,
Bogdan.
