     Use -o combined with -t (per the man page description of -o).

     Simple, no.
     
     One approach might be to return a magic character on EWOULDBLOCK and
     have a rule
     
     	.*<magic-character>	// put back .*, eat magic character
     
     This is off the top of my head, not sure it'll work.
