It doesn't, you have to add the "-lx" option manually. The --monitored 
does run things with a timeout (--timeout option). And if you don't 
specify that timeout it defaults to 5 minutes. I don't know all the 
conditions under which that monitor works though. But it's been shown 
that 5 minutes is usually not long enough.

Not that it's going to help in this case ;-) But I'll try. I looked at 
it briefly and it's not easy to add a meaningful message.
