Or just free up another register early on, like here.

If you're going to do that, you want to measure the impact on null
syscall performance though.

That should hold true for any change in that code, no?

Yes, but adding a gpr save is more invasive (you have to also load it
back later on & put it on the stack).

Cheers,
