#. FIXME .
#. When si_utime and si_stime where originally implemented, the
#. measurement unit was HZ, which was the same as clock ticks
#. (sysconf(_SC_CLK_TCK)). In 2.6, HZ became configurable, and
#. was *still* used as the unit to return the info these fields,
#. with the result that the field values depended on the
#. configured HZ. Of course, the should have been measured in
#. USER_HZ instead, so that sysconf(_SC_CLK_TCK) could be used to
#. convert to seconds. I have a queued patch to fix this:
#. http://thread.gmane.org/gmane.linux.kernel/698061/ .
#. This patch made it into 2.6.27.
#. But note that these fields still don't return the times of
#. waited-for children (as is done by getrusage() and times()
#. and wait4()). Solaris 8 does include child times.
