System.identityHashCode

[John Rose]

That’s a lame but correct implementation.  Making it higher quality will require some effort. An ideal implementation would make every bit of the output depend on every bit of the input that could affect the outcome of the acmp bytecode. And it would be fast. Therefore we have trade-offs to make.
