Fred, what did you use before Git?  All of the other DVCSs are atomic too.

CVS certainly had that non-atomic problem, and that drove me nuts.  RCS 
had it too, that's why CVS inherited it.  *The main* reason for SVN to 
exist is to "do CVS better" and one of the first things they fixed was 
that atomic problem.  OK, *everything* else they did was really odd 
but...they fixed the atomic problem.

Other than RCS/CVS I can't think of a major VCS that is not atomic. 
Maybe there are some small players...

Later,
JP
