Comment:

 My usleep manpage also says
 {{{
        The  interaction  of  this  function  with the SIGALRM signal, and
 with
        other  timer  functions  such   as   alarm(),   sleep(),
 nanosleep(),
        setitimer(),    timer_create(),   timer_delete(),
 timer_getoverrun(),
        timer_gettime(), timer_settime(), ualarm() is unspecified.
 }}}
 I can't see why it wouldn't work with `nanosleep`, though. I can't
 reproduce the problem.

 Can you attach the exact program (using nanosleep) that's being run, and
 the command line used to build and run it please?

 And can you check that `timer_delete` succeeds (it should return 0).
