This is something of an aside, but I'd be really interested in knowing
what it's needed for. A number of folks go around asserting that
CLOCK_MONOTONIC is not really monotonic on Linux, but according to the
documentation it is monotonic and the only thing non-"raw" about it is
that it can run slightly faster or slower when ntpd smoothly adjusts
for clock error. In particular, it ignores discontinuous clock
changes. If there's a bug and it sometimes is discontinuous, my
feeling is that the CLOCK_MONOTONIC constant should just be remapped
to CLOCK_MONOTONIC_RAW rather than leaving the standard clock broken
and forcing applications to use a nonstandard one...
