Ideally it should be the loader that says this and not the module
itself. As such I just removed these messages from the modules that do
this in trunk.

Well if I am understanding the code correctly, line 3267 of
org.exist.xquery.XQueryContext correctly, then it would seem to me
that all modules declared in conf.xml are instantiated for any XQuery
that is executed. Obviously this is not really desirable, we should
look to change this approach, perhaps one of -
1) Modules are lazy instantiated for an XQuery as they are required,
in this way an XQuery may declare a module but it need not be
instantiated unless it is actually used. Different paths of execution
through the query may mean that a module is never used in actuality.
2) Only required modules are instantiated at compile time, or first
execution. (These can be determined by the declared namespaces).
Cheers Adam.
