>Description:
Unlike most system calls, clock_nanosleep returns an error code, rather than returning -1 and setting errno.

I have written some calls that got this wrong, e.g. using the RL macro in atf tests (check for -1, report errno) when it should use RZ.

Time to audit all the callers for this class of mistakes!
