Comment (by simonmar):

 As we discussed on IRC, I'm not sure the comment about the speed of
 StorableArray is still true.  It probably dates from before we optimised
 the representation of `ForeignPtr`.

 A `StorableArray` allocated using `newArray` is on the Haskell heap, and
 GC'd as usual.  However, you can also make a `StorableArray` using
 `unsafeForeignPtrToStorableArray`, in which case the memory can reside
 anywhere you like (but presumably the `ForeignPtr` has a finalizer to
 deallocate it).

 Can I close this ticket?
