 // Is it permitted for the stubs above to refer to Object::null(), which is
 // allocated in the VM isolate and shared across all isolates.
 // However, in cases where a simple GC-safe placeholder is needed on the stack,
 // using Smi 0 instead of Object::null() is slightly more efficient, since a Smi
 // does not require relocation.
 
 // List of stubs created per isolate, these stubs could potentially contain
 // embedded objects and hence cannot be shared across isolates.
