 from http://lists.squeakfoundation.org/pipermail/vm-dev/2006-June/000748.html [^] -

Hi Folks -

Attached my proposed changes for both, the variable tracking as well as
the callback support. I'll respond in the individual threads about more
specific issues; let's leave this one to discuss the more "mechanical"
issues if there are any. Included files:

- ExtraGCRoots.cs: The change set for tracking variables in plugins
- Callbacks.cs: The change set for VM callback support
- ExampleCallbacks.cs: An example plugin making use of both of the above
features
- sqVirtualMachine[.h|.c]: The (updated) VM proxy

If you install all of the above and build a complete VM you should be
able to execute the ExampleCallbackPlugin's exampleCallback and
successfully compute 3+4 using a callback.

Let me know if you have any problems.

Cheers,
   - Andreas

 There are some differences between the contents of ExtraGCRoots.cs, Callbacks.cs and ar.70 on jabberwocky.

Am I right in thinking that the code in jabberwocky/ar.70 is more up to date than the code in the attached files? Is there still more recent code?
