Congrats, Vanessa; cool work.  Please see my reply to your System-codefrau.1205.mcz commit.

We have an effort crisis with the execution machinery.  You are asking did help. I am asking for help.  We have at least four different Squeak vm efforts.  Little mutual support.  Little community involvement.  Nothing new, but I do find this a serious problem. Thank you for tolerating my gloom in this holiday season.
