      Rust standardizing on libnative is the right move, IMO. The "evented" bits belong in something like Erlang I/O servers /cc @carllerche

      @bascule is libnative the one that just uses native kernel threads rather than reinventing them in userland?

      @bascule sweet. There's definitely a time and a place for userland threading, but I dislike the trend of using them just for the hell of it

      @charliesome my understanding is goroutines have similar behavior. Not sure how often people get tripped up by them

          @bascule @charliesome People don't get tripped up often. There is control of how big the native pool is and the lang has no thread-locals.

          @evanphx @charliesome I was wondering more about Goroutines not-being preemptive (I think?)

          @bascule @charliesome They're preemptive.

          @evanphx @charliesome doesn't it work kind of like a GIL, i.e. the goroutine needs to yield?

          @bascule @charliesome A goroutine gets a timeslice and there are checkpoints, yes. And goroutines can migrate between native threads.

          @evanphx @charliesome for a system call or long-running/blocking native call, it needs to yield to the scheduler though, right?

          Replying to @bascule

          @bascule @charliesome That's a special case. If a goroutine starts running code the scheduler can't see, it shunts it to special thread.

          @bascule @charliesome there's goroutine preemption since Go 1.2: http://golang.org/doc/go1.2#preemption … (design doc: https://docs.google.com/document/d/1ETuA2IOmnaQ4j81AtTGT40Y4_Jr6_IDASEKg0t0dBR8/edit …)

          @dchest @charliesome sort of preemptive except if they make a native call, kind of like Erlang and NIFs
