More Robust PID Faking in VECs

[insertinterestingnamehere]

In order to load CUDA into a VEC, we added support for faking the PID. (CUDA picks a port to use based off the current PID, so we can't load multiple copies of it without faking the PID). Currently we just make up a PID and hope for the best. It'd be nice if we could make this infrastructure more robust. For example, we could launch a separate empty process for each and then associate it's PID as the fake to use within a VEC. There probably are other options as well.
