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.
