+/* Some info tables to be used when compiled code returns a value to
+   the interpreter, i.e. the interpreter pushes one of these onto the
+   stack before entering a value.  What the code does is to
+   impedance-match the compiled return convention (in R1/F1/D1 etc) to
+   the interpreter's convention (returned value is on top of stack),
+   and then cause the scheduler to enter the interpreter.
 
-/* Since this stuff is ostensibly in some other module, we need
-   to supply an __init_ function.
+   On entry, the stack (growing down) looks like this:
+
+      ptr to BCO holding return continuation
+      ptr to one of these info tables.
+   The info table code, both direct and vectored, must:
+      * push R1/F1/D1 on the stack
+      * push the BCO (so it's now on the stack twice)
+      * Yield, ie, go to the scheduler.
+
+   Scheduler examines the t.o.s, discovers it is a BCO, and proceeds
+   directly to the bytecode interpreter.  That pops the top element
+   (the BCO, containing the return continuation), and interprets it.
+   Net result: return continuation gets interpreted, with the
+   following stack:
+
+      ptr to this BCO
+      ptr to the info table just jumped thru
+      return value
+
+   which is just what we want -- the "standard" return layout for the
+   interpreter.  Hurrah!
+
+   Don't ask me how unboxed tuple returns are supposed to work.  We
+   haven't got a good story about that yet.
