Does this include people running FreeBSD 4.X compiled programs on -current?
Even 6.x programs that use aio would be affected if 4.x ones were affected. I
think aio is the only thing 6.x and earlier could be using though.
So will there be some sort of compatibility shims? I bet that there
will still be a lot of 4.x binaries being run on 7.0 systems in the
future, just like 2.2.8 binaries were being run for years after 3.x and
4.x came out.
