Special thanks to:
* [David Carlier](https://devnexen.blogspot.com/) (@devnexen) for his many contributions, and making
mimalloc work better on many less common operating systems, like Haiku, Dragonfly, etc.
* Mary Feofanova (@mary3000), Evgeniy Moiseenko, and Manuel Pöter (@mpoeter) for making mimalloc TSAN checkable, and finding
memory model bugs using the [genMC] model checker.
* Weipeng Liu (@pongba), Zhuowei Li, Junhua Wang, and Jakub Szymanski, for their early support of mimalloc and deployment
