Right, of course.
OTOH, the safe version is far from useless.
I estimate (but haven't tested yet) that you would lose about 40 ms in
the Eee test case. That is, the boot-time savings are reduced from 123
to perhaps 85 ms which is still acceptable. It is certainly much less
complicated than the alternatives, so if that's what you would prefer I
can go that way.
I think if the cost is 40 ms once during boot on a slow platform, it's
worth unifying the two codebases. I am *not* saying that I don't think
boot performance matters -- far be from it -- but I think this is
probably worth the reliability and maintainability advantages of having
a single piece of code if at all possible.
Of course, if you can figure out how to avoid that and still have the
code clean, then that's another matter.

as long as LZO is optional.... and it's documented somewhere to not use
it if you want fast speed I'm totally fine.
