Overview

Extend into a class whose instances are shared across requests: new returns a frozen instance, so any later ivar write — e.g. request-time memoization — raises FrozenError instead of being a latent data race.

Must stay a new wrapper (never an initialize wrapper): the freeze runs after the entire initialize chain, so subclasses may assign ivars after super. Extending a hierarchy base covers its subclasses — singleton classes inherit along the class hierarchy.
