Well, what I had in mind was this: we'll need to
have a general allocation mechanism for all plugins,
so they can allocate memory, I/O ports, interrupts,
etc. When a plugin (which could be the debugger)
allocates an interrupt, when the interrupt occurs
it is reflected into the user program to the plugin.
When the plugin is done handling the interrupt it
can then specify to the kernel module
- either that the interrupt should ALSO occur
in the VM
- or that the interrupt is completely handled
by the plugin, in which case the guest never
notices the interrupt has occured.
