xref base issue #794 replaced but with an NYI routine:
{ "RtlGetUserInfoHeap", RTL_ROUTINE_GETINFO },
{ "RtlSetUserValueHeap", RTL_ROUTINE_SETINFO },
{ "RtlSetUserFlagsHeap", RTL_ROUTINE_SETFLAGS },

completely un-replaced and wrapped instead (which may be ok for some of these):
% grep -A 1 wrappi `ls -1td logs/D*|head -1`/g\* | grep interc
