We use a combination of locking the record using a simple boolean column
together with the user id who has locked the item and the timestamp.
The locking prevents another user from opening the form and happily
editing away without realising his changes will be lost when he presses
submit. The user id is to inform the second user who has opened the
document, and the timestemp is so that the first guy doesnt open the
document and go out for lunch leaving it locked. We default it to 5
minutes after which someone else can open the document and edit it.
