Okay then using the GsDeployer-style method, collect instances for each 
of your orphaned classes ... those with empty instance lists have class 
reference issues ... those with non-empty instance lists can be migrated 
ala GsDeployer-style method...

If you've already cleaned the known spots up,m then those classes with 
reference issues  can be resolved by finding all reference paths ...

Mariano and I went through a similar dance several weeks ago, and I 
published a gist with the tode shell script that collected info on some 
"orphaned classes"[1]  and I then produced an analysis based on using 
the script[2] ... at the end of the analysis I used the `./bug 
--references` to track down the reference to some of the orphaned 
classes ...

Slightly different scenario, but the `--references`, `--instances`, 
`--gc`, and `--reclaim` options might be interesting or useful in your 
own little analysis script ...
