@mvines These changes are old and in progress but I got stuck and this is blocking the loader optimization I'd like to put in. I added a comment at my stuck point, any suggestions? Another option is to pull the loader into runtime like system_instruction.rs |

Problem
Shared objects get their own instance of jemalloc so alloc/free of pointers across the shared object boundaries blow things up. There are outstanding load optimizations that require this and are currently blocked
