Sig, Please forgive me for being skeptical, but it is certainly worthy of a test on my end. How do the multiple processes coordinate access to the change log? Not having seen an IDE complain about access to either image or changes, and knowing that I have been bitten by this, I am not sure how to square it.

There is nothing wrong starting multiple processes using single .image file. During startup, vm just reads data from it. And when writing to an .image file, a process who first opens it should obtain a global lock on it, so nothing will have chances to interfere. So, it seems that image file was damaged or not written completely..
