Hi Sundar,

Thanks for all the detail - that sounds like a good approach to me!

TS makes a point of removing the guard files if Ruby exceptions are raised, but 
I guess the forced stop of DJ is a little more sudden. I guess it’d be nice to 
have this scenario managed by TS as well - I’m just a little unsure as to 
whether the extra complexity is worthwhile and can be reliable. Still, I’d be 
interested in seeing any patches for such an approach.

In the meantime though, what you’ve suggested sounds wise to me :)
