Hi all!

Indeed interesting times.

I am quite interested in the current crop of NoSQL databases and for 
example Riak - being my current "favorite" in that arena - has a 
map/reduce mechanism for doing lots of its parallell magic.

So it would be interesting to craft a "map/reduce" system in Squeak 
utilizing regular Smalltalk processes. Sure, you would need to know what 
the heck you are doing - but hey, I think that will be the general case 
for a few years to come until "magical languages" takes care of a lot of 
this for us.

And yeah, Igor's atomic stuff couldn't be more timely, right? :)

Will try to read between diaper changes. :)
