Removing this delay causes better synchronization between N clocks.

As I explained to you before: This is wishful thinking.

There is absolutely no guarantee that the syscall will yield better
results. It might on average, but that's a useless measure.

You also still fail to explain what this is going to solve and how it's
used.

Some user space applications need to read some clocks.

Is just not an explanation at all.
