Excellent question. If none matches, the module cannot be loaded. You 
will get an error message. If multiple files (module instances) match, 
then the current situation is that "the first one" wins. That means, it 
is currently important to keep the conditions mutually exclusive.

We got away with this non-design until now, but in 1.10 this will change 
to: multiple matching module instances are an error.
You will also be able to define an order for the instances by setting 
priorities. The matching instance with the highest priority is chosen. 
The exact formulation for the new behavior is: multiple matching module 
instances with the same priority are an error.

See QBS-61 and related patches for more information.
