It's OK if you reverse the default order - make it sideways if it gets a faster
Firefox. We can cope.

It's OK is you dump ctors for init_array if it simplifies your maintenance. We 
don't want you to be stuck with maintaining both systems.

But give us some (documented!) way to control how the init_array gets
populated, for when there's something you didn't think of in your planning.

Like "using command line order breaks when there are intra-library order
dependencies".

Please.

OK to re-open this ticket?
