Created a small solidity library for allowing arbitrary delegatecalls without the risk of storage collision attacks. Would love feedback on this approach!

That's exactly it. The idea is that storage inside this contract can be locked, protecting against storage writes during arbitrary CALLs or DELEGATECALLs.

Interesting. So this is a contract that any other contract can use for storage, and the storage space is a hash map keyed by the caller?

One thought: It looks to me as if it protects against arbitrary DELEGATECALL storage writes by opening up the risk of storage writes by arbitrary CALLs.
