I tried to write some C code that uses libaio to see how it works
before writing bindings and that worked with a simple file:

    int fd = open("testfile", O_RDWR | O_CREAT | O_TRUNC, 0660);

I had to piece the workings together from the undocumented header file
which kind of sucked. But the code seems to work.
