Actually I did run into trouble. CLOCK_MONOTONIC_RAW is defined in
linux/time.h and including that creates a lot of redefinition
conflicts with time.h. I see the linux/ includes aren't intended for
user space code.
Is this clockid meant to be of use to user space code and if so how
would one include the definition successfully? time.h is virtually
impossible to not have included if you're using most anything.
