First stack trace

I noticed a very high CPU usage during a minute or so. I *think* this happens some times when having the "layer.xml" file expanded (layer.xml in context). I haven't noticed this on other situations.

Not sure yet what ill effects would result from searching only within the same module. Probably too risky for 6.9.
