And it looks like we are keeping a very large amount of MC stuff; 13018 instances of MCVersionInfo/MCVersionName/DateAndTime/Date/Time/UUID. Is that smart? Simply flushing the cached ancestry from the MC browser gets rid of 60% of them and appears to save 3Mb. Except the damn saved image afterwards is exactly the same size! Sigh.

There is a reasonable solution for the release process, which is to modify the 32- to 64-bit bootstrap to allow the VM simulator to clone a 32-bit image having squeezed the free space out of it.  I'll try and get in this asap.  By year end I hope that Clément and I will have rewritten the compactor to eliminate this embarrassingly bad behaviour.

Argh, yes, I remember you mentioning this in the past.
