This transaction-local hash may be used as temporary storage by instrumentation that needs to pass data from one instrumentation point to another.

For example, if both A and B are instrumented, and A calls B but some piece of state needed by the instrumentation at B is only available at A, the instrumentation at A may write into the hash, call through, and then remove the key afterwards, allowing the instrumentation at B to read the value in between.

Keys should be symbols, and care should be taken to not generate key names dynamically, and to ensure that keys are removed upon return from the method that creates them.
