I can imagine. But what if you change only those variables that have
something to do with the fact that files are currently 32bit limited?
I.e., size, current position, a few things like that.

It seems fairly logical that adding a few cycles overhead to system
services that do I/O (i.e., spend lots of time either waiting for
devices, or moving bytes to/from cache blocks) is a non-issue.

I can understand an argument that this sort of change is tricky, but I
can't see a good reason why it should be a performance problem.
