.\" 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 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/ .
.\" Maybe it will make 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.
