I think he means Phobos/Druntime as shared library.

Yes separate shared libraries (with multiple runtimes) work on 
every other platform.
The problem for OSX is that onAddImage gets called for the 
executable and every shared library. It would be trivial to only 
register the image containing the current runtime, by comparing 
the address of a private symbol with the memory region of the 
images.
