Does not compile on stable nor nightly

[smups]

Compiling this crate generates build errors due to renamed items in the std allocator and incorrect (deprecated or non-existent) feature flags.

See cargo build output for details

Hey! Thanks for submitting an issue!

This has indeed evolved a fair bit since the code was written.

I would be very happy to review a PR if you have time to raise one!

aight I'll see what I can do; I'm having issues scaling my rust data analysis pipeline on multi-cpu boxes - I think it might be because of numa overhead.

There are a bunch of errors in the upstream allocator-suite crate, I'll fork that too.
