#.  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/ .
#.  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.

#.  FIXME: Maybe say something about the following:
#.  http://sourceware.org/bugzilla/show_bug.cgi?id=12889
#.      Rich Felker <bugdal@aerifal.cx>
#.      There is a race condition in pthread_kill: it is possible that,
#.      between the time pthread_kill reads the pid/tid from the target
#.      thread descriptor and the time it makes the tgkill syscall,
#.      the target thread terminates and the same tid gets assigned
#.      to a new thread in the same process.
#.      (The tgkill syscall was designed to eliminate a similar race
#.      condition in tkill, but it only succeeded in eliminating races
#.      where the tid gets reused in a different process, and does not
#.      help if the same tid gets assigned to a new thread in the
#.      same process.)
#.      The only solution I can see is to introduce a mutex that ensures
#.      that a thread cannot exit while pthread_kill is being called on it.
#.      Note that in most real-world situations, like almost all race
#.      conditions, this one will be extremely rare. To make it
#.      measurable, one could exhaust all but 1-2 available pid values,
#.      possibly by lowering the max pid parameter in /proc, forcing
#.      the same tid to be reused rapidly.
