I'd be interested to know if you can notice any performance degradation
associated with the VM itself versus earlier versions (as opposed to the
4.4 image). I think it has been fairly stable but a second opinion would
be appreciated.

This is a bit strange since the Scratch image runs ok on the older 4.0 vm and runs on the iMac with a 4.2VM. I've heard faint rumours of some Scratch related window updating issue so maybe there is a change in bitbltplugin? Anyone recall a relevant change?

Nothing comes to mind here. There was an issue with Scratch images that
prevented running on more recent VMs, but Bert fixed that and I think
you must be using the fixed Scratch image, otherwise it would not be
working on the 4.0 and 4.2 VMs. The low space condition sounds like some
other sort of problem, presumable early in the image startup. I can't
think what it might be though.
