Its related to CFC inheritance.  It seems to do some file operation
(on the parent cfc) when a CFC extends another CFC.

I made a new project with:

/foo/rootApplication.cfc - a copy of 
http://www.coldfusionjedi.com/downloads/application.cfc.txt
/Application.cfc - extends foo.rootApplication, but is otherwise
blank:

    <cfcomponent output="false" extends="foo.rootApplication">
    </cfcomponent>

/index.cfm - the default OpenBD index.cfm

A request results in the appstats (btw, you can run appstats on the
local dev environment):
