Ah, cool, thanks for letting us know. That's pretty much the same case I wrote it for (GitHub's shared-object-store fork repositories), but deployment got hung up on compatibility issues (since we used libgit2, as well). And then I never got around to it, and nobody seems to have cared too much. It's a nice safety to have, but I don't recall a single instance of an unintended naive gc ever destroying things. :)
