-// Used to "safely" transition from pointer-based runtime code to Handle-based
-// runtime code. When a GC happens during the called Handle-based code, a
-// failure object is returned to the pointer-based code to cause it abort and
-// re-trigger a gc of it's own. Since this double-gc will cause the Handle-based
-// code to be called twice, it must be idempotent.
