Your results caught me off guard. Particularly, the (linux) system allocator is too fast. I think the simplicity of the benchmark (allocating and immediately deallocating) might be causing issues... perhaps unwanted optimizations? I'm not sure.

On my random actions benchmarks (this resembles real allocation patterns somewhat better?):

- 1 thread: Talc is faster than Frusa and System, Frusa is comparable to System

- 4 threads: System is fastest, Frusa does about ~half as well, Talc does ~half as well as Frusa

Our benchmarks agree on the Frusa vs Talc comparison.

Benchmarks aside, Frusa seems neat. In particular, I had some misconceptions about how to tackle concurrency in Talc which Frusa's code demonstrates not to be true. I may give writing a concurrent version of Talc another shot soon.
