probably the VM crashed. In git version when squeaknos crashes it activates
an output console to debug and see what the error was

yes, I think you also have to uncomment a line in the Makefile related to
including this function from libc.

the git repo contains everything but image related stuff: helper scripts,
handwritten C code, makefiles, grub to install in hard disk images. We
started working on Squeak 3.9, then we moved to 4.1 and now we use Pharo,
but all dialects should still work (we even tried cuis once and worked
without big problems). I'll try to make a complete release tomorrow.

As for Cog, it should work just fine, but we haven't worked on it yet. The
only thing that should be needed is to port the makefile, and for that we
have to talk to Eliot to get some clues.

Well, that would be a nice experience, I think that exploring security in
NewspeakNOS can be really interesting hehe. Let us know what you find out.
