Sub-domains should work also then. Just make a page with bunch of IFrames, each on a different, random sub-domain.

Edit: Ooops; didn't see the comment above about sub-domains. Worth a try though!

A malicious actor might write a wordpress worm to assemble a domain botnet and cross-link them all to each other such that visiting one stores 5 megs of nonsense from every site on a visitor's client.
