Summary: invalid ref in ThreadSetResult

Initial Comment:

ThreadSetResult gets a pointer
to the string rep of an interp result:

    result = Tcl_GetStringResult(interp);

then keeps on using that pointer after
the interp's doing other things, making
no effort to preserve the result.

Recent changes on the Tcl HEAD allow
that result to change out from under us.

Here's a simple patch to correct.
Without it, you will see tests fail.
