  // KrollCallback is a wrapper around a JS function object which is passed

  // side as a normal opaque object and then passed back through to Kroll
  // for function invocation (or just to pass the function object back as-is)

  // KrollCallback has one fatal flaw: It can lead to retention loops. So when a
  // function is to be a property of a proxy, we store this on the JS object. But
  // if the proxy spans multiple contexts, we need to take a rain check on other
  // contexts.
  
  // In the mean time, for functions passed as a property between contexts, we
  // need a lightweight wrapper. This is probably not the best way, but this
  // should be sufficient for 1.7 in the edge case of one context needing to call
  // another context's function.
  
  // Until KrollObjectProperty and such are addressed in the future, this is an object that is never
  // made explicitly by TiIdToValue; instead, all JS functions become KrollCallbacks, and both
  // KrollCallbacks and KrollObjectProperties will be converted into functions (or TiObjectRefs at
  // any rate)
