Parallelism, concurrency, etc.

[emk]

There are many different kinds of parallelism and concurrency, and one size does not fit all in Rust (or in general), unfortunately. :-/

• rayon seems to be an excellent choice for things you might describe as "data parallelism" or "parallel iterators". But if you don't fit that particular use case, it's not applicable.
• Anything involving queues and workers will need a very different sort of library. I'm not sure what's currently being used out there.

I've picked up on your exact sentiment through lots of comments and reading lots of other lists, I'm going to change the subcategory for now (c15a7d2)

I think this should be a category with a couple of sub categories in its own right, any suggestions?
