  Removed in POSIX.1-2008.
  POSIX.1-2004 specification: @url{https://pubs.opengroup.org/onlinepubs/009695399/functions/usleep.html}
  
  Gnulib module: usleep
  @mindex 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:
  NetBSD 10.0, mingw.
  @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.
  @item
  On some systems, @code{usleep} may sleep for less than the indicated duration:
  Cygwin 3.5.3.
  @end itemize
