14:05 < ecr> olsonjeffery: it'd involve
- designing an RtioTimer interface in std::rt::rtio.rs,
- implementing Timer in std::rt::io on top of it,
- implementing RtioTimer for TimerWatcher in std::rt::uv::uvio.rs

14:09 < ecr> olsonjeffery: and you might want to look at the libuv timer interface as well to see if there's any additional functionality that still needs bindings (which would 
             give you the bottom layer of newsched I/O in std::rt::uv::uvll.rs).
14:12 <ecr> if I'm not responding in IRC, try email ([email protected]).
