Because of the root user issue, and also because I don't care about that much at the moment. I'm still experimenting and for those experiments it doesn't matter which VM I use. Thirdly, the itimer VM is the one I get when I use 'curl get.pharo.org/60+vmLatest <http://get.pharo.org/60+vmLatest> | bash', which is convenient to get the latest VM, and to minimise differences between the VM's we built the same one. I will definitely consider using the threaded VM for production.

Well, it does work already, just not when we build the VM ourselves :/

Cheers,
Max
