Basically I gave up on this. My change made things worse, and while I
still didn't get the point (read: For my understanding there's a
discrepancy between the syscall's description and what actually
happens), it's certainly better to keep things the way they are.

Since, as I presume, this has no impact on performance, this boils down
to aid a human reviewing the code in understanding what's happening
here.
