Rails 2.3.2.1 ActiveResource objects are frozen?

Hey all,

I've dug through the code and bit and cannot figure out how or why this
is, but between Rails 2.1 and 2.3.2.1 production ActiveResource objects
became frozen upon retrieval.

so:

Shoot, it looks like we have some Rails.cache being called. I think I
noticed objects pulled out of memcache being frozen. Is there a reason?
Who knows.

Uh, now I just can't configure the cache:

Ended up with this:

Anything written to any cache will be frozen. Bug at the worst, REALLY
unexpected at the best.
