13337,io_service::stop() behavior on MSVC contradicts documentation,Diego Barrios Romero <eldruin@…>,chris_kohlhoff,"The io_service::stop() documentation says:
>  [...] All invocations of this run() or run_one() member functions should return as soon as possible [...]

This is the behavior observed on GCC but not on MSVC.

Reproducer code:


{{{
#!cpp
#include <boost/asio.hpp>
#include <thread>
#include <iostream>
using namespace std::chrono_literals;

int main() {
    boost::asio::io_service s;

    s.post([] { std::this_thread::sleep_for(5ms); std::cout << ""1\n""; });
    s.post([] { std::this_thread::sleep_for(5ms); std::cout << ""2\n""; });
    s.post([] { std::this_thread::sleep_for(5ms); std::cout << ""3\n""; });

    std::thread th([&] { s.run(); });

    std::this_thread::sleep_for(1ms);
    s.stop();

    th.join();
}
}}}

This prints ""1"" on [https://wandbox.org/permlink/N02wy78yFGX1eJRl GCC] but ""1 2 3"" on [http://rextester.com/FHNW43260 MSVC]
