Why does Doctrine\ORM\Configuration's “DoctrineProxies” Object contain the Universe?

Question

In my ORM code I have an Entity with a field fined like so:

//part of entity class Item:
/** @Column(name=\"product_id\", type=\"integer\") */
private $productId

You can't dump a proxy object without XDebug or similar tools (which limit the dumped object size).

The problem is really, really simple:

Proxy -> references EntityManager -> references UnitOfWork -> contains Proxy

This obviously leads to a recursive data-structure dump, which in turn leads to a mess any time you try to dump it without sensible limits.
