DNS lookup stalls as motivating concurrency .. messy, complicated code with known bugs .. seriously? It's not that hard to call getaddrinfo() in a thread and feed results back (atomically) over a pipe. No shared memory or mutexes needed. Looking at Android as a representative of "embedded" also seems a bit fallacious. The lowest-end android device I can buy has a lot more ram, storage and clocks than an average home router. EDIT: this comes across pretty snarky - more so than is warranted. I'm surprised by the first part, but have no right to impugn the whole project based on that. The surprise remains, but I apologise for my tone.

Depends on the situation, if you are in a server that needs to handle millions of requests and you create a million thread probably wont fly. If your concurrency is limited to a low enough number than you can create and terminate threads, so the proposed threading solution works well on mobile devices.

DNS gets so much blame, and yet so little time is spent to make it better. If DNS is that important to your application, you should install a caching resolver locally on your system.

Well you can look at ARM Cortex-M3 running MicroEJ instead. http://www.microej.com/resources/supported-platforms/ http://www.microej.com/resources/supported-platforms/

  I don't understand the relevance?

    MicroEJ OS, a Java based OS for micro-controlers like the ARM Cortex-M3, with 128 MB NAND FLASH + 512 kB internal for storage and 32 MB SDRAM + 96 KB internal for program data, running at 12 MHz is far away from the average Android device configuration, yet can still run a mix of Java/C stack.

      OP: go has an interest in suiting embedded because Android. Me: Android doesn't need to meet constraints anywhere near a home router (which needs to run ntpd) You: there's a proprietary Java-based OS for Cortex-M3 .. still don't get it. Are you trying to sell me something?

        That there are Android like OSes that run in hardware less powerful than home routers.

        The relevance of Android here is that Go has a reason to target it. Not that it's a Java/C hybrid.
