Thanks for the suggestion. Unfortunately, though, I don't think
async_read_some() is going to work for me. Here is an excerpt from
How do you obtain the file descriptor?
It's just a native POSIX file descriptor created with open(), like this:

int open_pin(unsigned int number)
{
  std::ostringstream filename;
  filename << "/sys/class/gpio/gpio" << number << "/value";
  return open(filename.str().c_str(), O_RDONLY | O_NONBLOCK);
}
