Some notes:
All components should be kept in a memory pool (one memory pool for one component type).
Components should be as small as possible - they should contain only "configuration", all additional data (e.g. shadow map pointer for lights) should be managed by an appropriate system. Components will usually create some kind of system proxy when it's possible, e.g. when mesh resource was loaded.
