   I saw nowhere this requirement is written.
   Plugin factory, BTW has the same quality, so I really don't see a reason for 
a separate 
class.
   Every plugin module already has unique marker, it is handle returned by 
LoadLibrary()/dload(). What is a second one for?..

   Separate exported function can do the same but don't require to implement 
unnecessary 
methods (including ridiculous in this case getModule()).

   What if a plugin does not require any special cleanup? Can it return NULL 
from 
getModule()? Is engine ready to get this NULL from it?
