Comment:

 The core of this is now done, and we use the .a files on OS X. There is
 still some polishing to do (e.g. it currently always uses mmap to allocate
 memory for the object files, and maps memory separately for each
 individual object file), so we won't do it in time for 7.0, but it's
 entirely feasible for 7.2.
