# Test various new() invocations - this is all about backcompat, making 
# sure that insert() still works as expected by legacy code.
#
# What we essentially do is multi-instantiate objects, making sure nothing
# gets inserted. Then we add some more objects to the mix either via
# new_related() or by setting an accessor directly (or both) - again
# expecting no inserts. Then after calling insert() on the starter object
# we expect everything supplied to new() to get inserted, as well as any
# relations whose PK's are necessary to complete the objects supplied
# to new(). All other objects should be insert()able afterwards too.
