I'm not sure about that, but I had a couple of issues

Is/can that be true?
Yes, that's definitely true. Tcl_GetObjResult() *can* return
a shared object.
If yes, one should avoid constructs like:
Tcl_SetStringObj(Tcl_GetObjResult(interp), thestring,
stringlength);
Yes, one should absolutely avoid such constructs.
It can lead to Tcl_Panic()s when you least expect them.
There used to be a number of them in the core, specifically
the idiom:
Tcl_AppendToObj(Tcl_GetObjResult(interp), ...);
as a replacement for Tcl_AppendResult(). Fortunately most of
these have been fixed by now.
and use:
Tcl_SetObjResult(interp, Tcl_NewStringObj(thestring,
stringlength));
instead [...]?
Yes, do that instead.
