Here is what I suggest.
- Keep a log of these fixes may be on the cog vm
- did you publish your fixes using the git infrastructure we put in place - because without it we will not work.
- Write some tests
- Soon igor will resume his work on vm building with hudson and we should get some regression testing tests.
- Soon we should be able to introduce these changes and evaluate their impact.
- we should push the git infrastructure.
