+// Bug 1221378: allocating an array from within the object metadata callback
+// shouldn't cause re-entrant resolution of lazy prototypes.
+
+// To test for this regression, we need some way to make the code that collects
+// metadata about object allocations allocate an Array. Presently,
+// enableShellObjectMetadataCallback installs a callback that does this, but if
+// that hook gets removed (in production there's only ever one callback we
+// actually use), then the ability to make whatever metadata collection code
+// remains allocate an Array will cover this regression. For example, it could
+// be a flag that one can only set in debug builds from TestingFunctions.cpp.
