You are right. It seems there is no reason for it.
clock_nanosleep is internally using a syscall.

I prepared attached patch and running the regression tests.

Do you like to test or review?

I cleaned up old code, which might be only required for Linux
kernels older than 2.6.0, which I do not going to support anyway.

best regards
 Waldemar
