Thank you Reid, that makes alot of sense now. Is there an API to the JIT functionality? If so, <div>could you point out where in the code base it lives, and if there are examples of clients (how to</div><div>use it?)</div>

</div>Yup, it works similar to the way debuggers find out about dynamically<br>
loaded libraries. There's a particular loader stub that gets called<br>
after every library load or unload. Debuggers put a breakpoint on it<br>
to stop the inferior process and re-read the list of loaded libraries<br>
with remote memory examination routines, so there's your (hacky) IPC.<br>
