The problem with
 factory.addStep(CommandToSetProperty(buildnumber=getBuildNumberFromAnotherDB())
is that it will be executed at configuration time - which is probably
not when you want to get that build number.  What makes a lot of this
awkward is that you want to run Python code at a particular time in
the build process.  Subclassing MasterShellCommand is the best way to
do this.
