-This macro is used to construct a MallocPtr on the heap after a ccall.
-Since MallocPtr's are like arrays in many ways, this is heavily based
-on the stuff for arrays above.
+[Based on previous MallocPtr comments -- SOF]
+
+This macro is used to construct a ForeignObj on the heap.
What this does is plug the pointer (which will be in a local
-variable), into a fresh heap object and then sets a result (which will
-be a register) to point to the fresh heap object.
+variable) together with its finalising/free routine, into a fresh heap
+object and then sets a result (which will be a register) to point
+to the fresh heap object.
+
+To accommodate per-object finalisation, augment the macro with a
+finalisation routine argument. Nothing spectacular, just plug the
+pointer to the routine into the ForeignObj -- SOF 4/96
Question: what's this "SET_ACTIVITY" stuff - should I be doing this
too? (It's if you want to use the SPAT profiling tools to
heap-checking, etc. -- see Ticky.lh. It is quite specialized.

+(Swapped first two arguments to make it come into line with what appears
+to be `standard' format, return register then liveness mask. -- SOF 4/96)
