Can you help me apply a Bridge pattern to an exisitng class design?

As you can see I have an interface for Debug Events and two operations Attach and Detach. On top of this I have to implement a Windows and Linux version so the current design does not scale at all.

Imagine that I have to add:

• DebugEventThread <- DebugEventThreadAttach <- DebugEventThreadDetach
• DebugEventProcess <- DebugEventProcessAttach <- DebugEventProcessDetach

This design blows out of proportions...

I know Bridge pattern would be a solution to this problem but I don't know how to apply it in this case.
