* marker used to distinguish between memory, which has to be
* freed (in that case the marker is FREE_MARKER_IS_ALLOCATED
* [0xfefefefe]) or memory, which must not be freed as it is a
* string residing in the receive buffer of a request (in that
* case the marker per GIOP is the length of the following
* string, thus some number guaranteed to be smaller than
* 0xfefefefe, I don't think, we ever support transferring
* strings with a length of 4GB ;-)
*
* The marker is not 0xffffffff, because that is also -1.
* Remember that the length in the receive buffer can have
* swapped endianess, so using 0xffff0000 is a plan to
* disaster.
