Yep, sorry I haven't replied to your related email on event
throttling... still trying to catch up on digesting all the emails!

I think this hard limit could be made configurable by adding a new
class/service pair. E.g.:

template <typename Allocator = std::allocator<void> >
class limits_service

template <typename Service>
class basic_limits
  basic_limits(demuxer_type& d);
  void post_queue(std::size_t value);
  std::size_t post_queue() const;
  ... and so on ...

typedef basic_limits<limits_service<> > limits;


boost::asio::demuxer d;
boost::asio::limits l(d);

Any suggestions about what sort of numbers should be used by default?
