-   sysconf(_SC_CLK_TCK) is best, since it's the actual running kernel, not
-   some compile-time CLK_TCK.  On glibc 2.3.2 CLK_TCK (when defined) is in
-   fact sysconf(_SC_CLK_TCK) anyway.
-
-   CLK_TCK is obsolete in POSIX.  In glibc 2.3.2 it's defined by default,
-   but if you define _GNU_SOURCE or _POSIX_C_SOURCE to get other features
-   then it goes away.  */
