Hey folks:

In a rails app I'm building, the home page will have two forms:  one to 
sign-up for an account, another one to sign-in to an existing account.

Now, if I were to use object form helpers to build these forms, the 
controller for the homepage would need to create instances of the relevant 
models each time someone visits the homepage.

This concerns me a bit, because a visitor to the home page may or may not 
end up using either the sign-up or sign-in forms.  For instance, they may 
instead click a link that gives a "tour" of the app.  If they do so, will 
the instance variables created by the controller in anticipation of the 
POTENTIAL use of the forms be garbage-collected?

I'm just thinking about efficiency here -- don't want to have a bunch of 
extra instance variables taking up space in the runtime memory just for the 
sake of the (slight) convenience of using model object forms helpers rather 
than plain-vanilla form handlers.

Thanks!
