Suggestion: We should make sure we can accommodate F2003 with 4.2 and 4.3 by increasing the possible number of flags as needed.
I'm in favour of that, and I already started writing the necessary patch. But it looks like we'll have to bump the so number a last time, for 4.3, and then make the private part of the structure wider, to accomodate any new flags (for things like extension, or the way we'll really handle asynchronous I/O).
