+ * DESCRIPTION
+ *
+ *    Sets global SilcStack `stack' that can be retrieved at any time

+ *    to the current thread.  Each thread can have their own global stack.

+ *    thread.  If the global stack has been set already, new call will
+ *    replace the old one.
+ *
+ *    This routine is provided only as a convenience function to store
+ *    program's or thread's stack in one global place.  It is not mandatory
+ *    to call this function in order to use SilcStack.
