As soon as it is ready .
I would have liked to say "now", but we unfortunately our latest invention in the debugging area gives a stability problem in the debugger.
The idea is to run so-called presenters in the debugged program. The presenter will describe how the values are going to be handled in the debugger
But it is rather difficult to run code in the program when the other threads have been suspended, because these threads may hold a lock that is also required by the presenter-thread. And since a suspended thread will not release any locks the presenter-thread may be blocked until the program is again resumed.
We are currently working on a "controlled thread resume strategy" which will be used to unblock the presenter-thread. We will release, when that is implemented (provided that it solves the problem).

- how they are going to be written and
- how they are going to be expanded
