Bear in mind that making the entire structure 'packed' means
gcc treats it as being potentially completely unaligned
(ie attribute 'packed' means 'packed and not at all aligned',
not just 'packed'). This isn't a big deal except for structs
where we care about atomicity, though, which I don't think
is the case here.
