Yeah, that might be an issue. Note, however, that the lock-based variant
differs substantially from what's been published. And I sort of doubt
their patents covers a lot of stuff that's not lock-free-ish.

But again, I'd also very much welcome any other allocator. In my
opinion, it's the most annoying drawback of the process-based design
compared to a threaded variant (from the perspective of a developer).
