You should only get EINTR if the file was not ready for reading.
This should never happen if you properly set yourself up,
for example with g_io_add_watch.

If you get EINTR it is a sign that you should have called
polled the file descriptor first or you should make the fd nonblocking
so you really will get EAGAIN.
