Comment (by simonmar):

 Simon, this is pretty well documented already in `Storage.c`, all the
 points you mention are already covered.  In fact some of it is *also*
 documented in `StgCmmBind`.  I suggest:

 * remove the comments in `StgCmmBind`, replace with a pointer to
 `Storage.c`.  Multiple comments describing the same thing are bad, because
 when making changes we'll tend to only update one of them.

 * edit the comments in `Storage.c` to bring them up to date with the
 changes.
