Now it is not possible to get notification about process instance end, suspend 
or resume in module instance associated with the process instance. Sometimes it 
is required in order to perform additional logic in external modules. 
As an example we could look at JBPM built in module instance TaskMgmtInstance, 
which already get's notified about process instance end, suspend and resume 
using custom methods and additional logic in token class. (on process instance 
end removeSignalling(token) method gets called, on suspend/resume 
suspend(token)/resume(token) method is called)

So as a solution end/suspend/resume methods of token might be changed and 
notification might be send to all registered module instances. We probably need 
per token notification, so that all possible requirements could be fullfilled 
i.e TaskMgmtInstance requires exactly per token notification, in our 
application we need only process wide notification.

What do you think ?
