Yeah, I first thought of this. But went with including the module as the path 
is printed to the user. Couldn't a smart server script grab the content of the 
latest folder added under .instant/error?

Not sure this will be a problem. Isn't the "only" thing that might happen is 
that one file gets overwritten by the other? But I still think including the 
hashed module name is cleaner.
