The following asio library calls may throw, and we should not call them from within NetworkInterfaceASIO. Many of these methods have non-throwing variants:

asio::io_service::run()
asio::system_timer constructor
asio::system_timer::cancel()
asio::system_timer::expires_at(time point)
asio::system_timer::expires_after(duration)
asio::system_timer::wait()

This list may not be exhaustive.
