I don't know if there is a way around it, but I believe that is expected 
behavior, though incorrect behavior.  The programs should close STDIN 
and STDERR, but if they do not then things hang.

I ran into this trying to get some programs to run during system startup 
in initialization scripts.

The real question is: can cfengine work around this?  I believe you can 
use a shell script to "hold" the process which doesn't close STDIN and 
STDERR properly.
