Of course i forgot one:

Plugin ==> Core
Plugin ==> System (for SharedLib-related support)
System ==> Plugin (MimeHandlerFactory is-a PluginManager)
IO,Net,Sql ==> Plugin

This one is a bit trickier to fix. The straightforward solution would be 
to move Plugin to System. This makes sense, actually, because Plugin is 
just an subclass of Factory which knows how to handle native DLLs.

The problem with that move would be (IO <= Plugin => System). Damn...
This dependency is tricky, but there is potentially another solution:

Move PluginManager to the core, removing any System-related API.
Create new type System/NativePluginManager (extends PluginManager), and 
move the System-related API here. NativePM will silently swap in the 
SharedLib support to PluginManager, in the same way that PluginManager 
can swap out the Factory<>::instance() objects.

That might work. i'll need to experiment... tomorrow...
