 New Revision: 251078
 URL: http://svnweb.freebsd.org/changeset/base/251078
 
 Log:
   sleep: Improve nanosleep() error handling:
   
    * Work around kernel bugs that cause a spurious [EINTR] return if a
      debugger (such as truss(1)) is attached.
   
    * Write an error message if an error other than [EINTR] occurs.
