It's not all that bad, as it would be only used for those freeProcs
that do not really free() the pointer, such as e.g. TCL_STATIC, (which
isn't even a function in the first place).

Since TCL_STATIC and TCL_VOLATILE seem to cover almost all the 
usages, anyway, my original idea of having to change exactly those
to using some Tcl_SetResultRO(...) seems indeed not so good now.

I do not understand all these things that I seem to have triggered,
(especially in your second reply) only so far as that they have little
to do with what I suggested.  If they lead to a better approach, I'm
nevertheless happy :-)
