Implementing an atomic wizard with new objects

Hello after having searched the forums I couldn't find any soution to
this problem:

I want to implement a multi step form across models.

Step 1: Enter requested username/ password - User model
Step 2: Enter Profile information - Profile model
Step 3: Misc questions - Questionaire model
Step 4: Accept settings and save

The problem is if a user is created in step 1 and then exits his
browser during step 2, thus a record in the users table is dangling,
no good.

The best solution would be to have a Wizard controller with each step
being associated with a method. Ive looked at the Wizard plugin
(http://github.com/crankin/wizard/tree/master), however it doesnt seam
like it addresses the issue mentioned above.

and also problem with back button in the browser,what if the user
press back at step 3 and goes back to step 1 and start it..offcourse
we can update it using update_attribute but it create many round trip
to DB

Ive also looked as acts_as_statemachine but I dont know how I can get
it to work with e.g. the wizard plugin.

Thanks in advance

Please solve this problem. I'm trying to sign up, and don't notice the oncoming electrical storm. On page 2 the lights go out. When I reboot and recover, 59 minutes later, I should be able to resume page 2.

Save your dangling records, and allow some innocuous event, such as someone hitting a list of users, to reap the danglers that are older than one day.
