I would suggest to stdout/stderr point to options["debug_fh"] so we can 
use this information.

imho this function is not needed because you have to check and control 
this after each subprocess.Popen() ; if you believe it is a good idea to 
have such function (I'm not totally against it) then put it in fencing 
library.

I have no other comments, good work
