You could try just make the change to the identity_map plugin to use a
thread-safe global hash instead of a regular hash stored in a thread-local
variable (changing identity_map and identity_map=). But you are going to
have to use some sort of locking mechanism at the model instance level to
make sure that no thread is modifying an instance while another thread is
operating on it. I'd recommend writing a mutex plugin so you can do
model_instance.sync{...} for that.
