Hey Jigal,
I guess technically this bug could occur anywhere that exec() is used 
but its just the case that we only see it in image processing right now?

Adding a wrapper for exec() would fix it everywhere (in the theoretical 
cases we haven't seen), but would expand the scope of the patch so I'm 
not sure if its worth it or not.  What do you think?

Thanks!
Jeff
