RE: Multiple shunts

Even if you are using singleton controllers (say FormBeanUser), you
still need to keep the Form object somewhere - that would be the
HttpSession attribute collection.  Any data shared inside a singleton
controller will be shared among all requests from all users and would
need to be protected by synchronization.

Assuming you are trying to populate a form across several invocations
using FormBeanUser, just write makeFormBean() like this:

Get bean out of session attributes
If bean does not exist
    Create bean
    Save in session attributes
