There is not much CFEngine can do about kernel bound things like I/O,
except to try to kill the source process.
Unfortunately, Linux does not support sigalarm timeouts in a lot of
calls so it is hard to know when something is hanging. The usual
approach for debian systems is this:
body agent control
{
environment => { "DEBIAN_FRONTEND=noninteractive", "LANG=C" };
}
