work shedding via the codel algorithm

[dtaht]

I have been considering doing some new work in rust on the bufferbloat front. I see a lot of userspace networking being done with fixed or unbounded length fifos, with their inherently problematic properties. I'm also big on having the ability to have a thread scheduler that can queue and give up on new work in bounded time, (bufferbloat is not just a networking problem!), much like how uber implemented a codel like algorithm in go over here:

Codel: https://queue.acm.org/detail.cfm?id=2209336

All that said, me going from ground zero to hacking on generics, tokio and std::collections is proving difficult for my aged brain to handle, but I thought that perhaps those reading over what uber had accomplished might inspire some to think about work shedding in general, in rust.

ok, crossbeam looks like a start...
