Comment (by artyomtnk@…):

 To be honst, from my knowlege of boost.asio and my implementation
 of fork aware boost**er**.aio for CppCMS I don't think this is quite
 simple feature to implement, few points:

 - Reactor should be created, first time only after fork, probably on call
 of io_service::run, otherwise, its file descriptor (for
 epoll/depoll/kqueue) would be shared between processes.,
 - Select interrupters should be created after fork as well as it my be
 shared between processes as well and lead to very bad bugs.
