Okay now I'm more awake, lets see what we can do.

The problem you're hitting is there is no real load/unload hooks by the 
looks of things.

Okay assuming DllMain is in fact being called correctly, you can 
initialize and unload D's runtime.
So you can build reloadable platform fairly easily there.

You'll need to test that you can in fact fully load/unload D's runtime 
more than once.
Unfortunately I don't think you can modify LabVIEW from D side.

I've done a bit of reading on how to make it so GetProcAddress returns 
whatever you want (runtime adding of symbols).
Simply put, do-able!
