This minute, I just realized the same ...

Sort of. Finished the library part.

Btw, CPU_TIME has a fallback implementation using times(2). As "times() 
returns  the  number of clock ticks that have elapsed since an arbitrary point
in the past", it is IMO unsuitable to be used with CPU_TIME. CPU_TIME is
supposed to return a "value representing the elapsed CPU time in seconds [since
start of the program]". Thus, I ditched this fallback for the common
implementation.
