(Whiteboard: [MemShrink:P2])

dladdr() is incredibly slow on OS X. I tracked this down to Apple's implementation[1] of looking up the closest symbol which enumerates every symbol in an image each time dladdr is called. Maintaining a sorted list of symbol addresses would vastly improve lookup times. It's possible we'd want to use this outside of DMD as well.
