  POSIX specification: @url{http://www.opengroup.org/susv3xsh/usleep.html}
  
  Gnulib module: usleep
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On some systems, @code{usleep} rejects attempts to sleep longer than 1
  second, as allowed by POSIX:
  mingw.
  @item
  This function is missing on some platforms.  However, the replacement
  is designed to be lightweight, and may round to the nearest second;
  use @code{select} or @code{nanosleep} if better resolution is needed:
  IRIX 5.3, Solaris 2.4, older mingw, MSVC 14, BeOS.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  According to POSIX, the @code{usleep} function may interfere with the program's
  use of the @code{SIGALRM} signal.  On Linux, it doesn't; on other platforms,
  it may.
  @end itemize
