First try - BOOM! (Re: [Vm-dev] Re: [squeak-dev] Teleplace Cog VMs are now available)

Howdy!

First: Super fun and cool! I am of course *very* happy to see Cog released.

Now, over to some "testing"...

SIDENOTE: First btw I ran pystone.py with regular Python 2.6.5 on my 
Lucid Lynx, then in the latest "regular" VM from Squeakvm.org. Result:

Python: 36k pystones
Squeak: 45k pystones

So... the good ole VM is still a tad faster than CPython in that bench. :)

Now, I wanted to try it out with Cogit. Trouble begins! :)

I am using the tar ball on a Lucid laptop.

1. vm-sound-NAS does not compile! Lots of compile errors, probably due 
to a new upstream NAS. So try to get rid of that plugin... is harder 
than I thought! I finally ended up hacking the configure script to 
"fail" on the compile check by trying to compile rubbish. ;)

2. For some odd reason this will still create duplicate lines about NAS 
in disabledPlugins.c, just manually remove one of them, fine. Tada! Got 
a VM binary.

3. Fire it up on a *vanilla* Squeak4.1.1.image. BOOM, segfault. This is 
a "full debug VM" per instructions in HowToBuild. Anyway, see all info 
below, and tell me if there is more you want. :)

Btw, is there some nice existing script to run to "collect data about 
the box" that does uname etc?

regards, Göran
