 // NOTE NOTE NOTE
 // Write barrier note: the container for a HeapMultiname is *not* 'this';
 // HeapMultiname figures as a field in eg QNameObject and XMLListObject.
 // You *must* call FindBeginningFast(this) to get the right container.
 //
 // NOTE NOTE NOTE
 // This version is only safe if 'this' is on the first block of the object - because
 // GC::GetGC() is not reliable otherwise.  See bugzilla 525875.  Use the more
 // reliable version below if in doubt.
