I did hack gcx.d, but only to make the global mutex public. The implementation is relatively simple. My ticket submission failed when I tried to submit it, so I emailed Sean directly. That was months ago, and I never heard back. I'll resubmit a ticket... 

Theoretically, a weak ref might naturally tie into your precise scanning changes. Admittedly, it's the dereferencing that is tricky to get right without hacking gcx.d.
