The change to nanosleep.2 seems mostly fine. Except that the
term "requested relative duration" (line 142) raises questions;
what about changing that to "requested duration"?

Yeah, I had doubts about that one.  Probably I should drop 'relative'.

The change to clock_nanosleep.2 seems wrong. There are two cases
(quoting the old text):

       If flags is 0, then the value specified in request is interpreted
       as an interval relative to the  current  value  of  the  clock
       specified by clockid.

       If  flags  is  TIMER_ABSTIME,  then request is interpreted as an
       absolute time as measured by the clock, clockid.  If request is
       less than or equal to the current value of the clock, then
       clock_nanosleep() returns immediately without suspending the  calling
       thread.

In the first case, the argument is a duration. In the second case, the
argument is an absolute time point; it would be wrong and very confusing
to denote it as "duration".

Hmm, thanks!  I guess we'll have to keep 'request' in clock_nanosleep(3)
unless someone comes up with a better name.  Elliott, you may want to
partially revert that change in bionic.

Have a lovely day!
Alex
