i think it's ok

     rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
     geteuid32()                             = 447

     rt_sigaction(SIGINT, {SIG_DFL}, {0x80a1ff4, [], SA_RESTORER|SA_RESTART, 0x3710d8}, 8) = 0
     exit_group(0)                           = ?


so all that's happening is a dup2.  in that case there should in fact be two
fds (fileno).
