notes for newsched work

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).

--------------------------------

12:07 <@brson> olsonjeffery: in #6855 we want to make it so that it's possible for Tasks to be backed by pthreads, not green threads. so for #4770 we would want to have rt::comm 
               (newsched pipes) able to change the way it does synchronization based on the type of Task it's interacting with. I don't think though that it would use a trait for 
               this because the behavior is very dynamic - e.g. pipes can be sent from green threads to non-green threads

13:48 <@brson> olsonjeffery: #6164 #6846 #6168 #4248 #6210 #6167 #5021 #6844 #1226 are all important and not (very) blocked on things. a lot of them involve implementing new I/O 
               types. this thread contains descriptions of the most pressing issues: https://mail.mozilla.org/pipermail/rust-dev/2013-May/004305.html
13:49 <@brson> olsonjeffery: there's also porting various concurrency types that i haven't looked at, mostly in extra::sync and extra::arc
