Reverting revision 1345849 because it is not thread-safe and it doesn't work.

It appears this was an attempt to create per-tenant FOP factories, but instead each tenant overwrites other tenant's FOP factory instances.

A proper implementation would require a FOP factory cache keyed by delegator name.
