I had the same idea but the build history is quite short (7) and with
our updating speed it is filled within two days :-) I extended the
builds count yesterday to 20.

The next interesting information about dzindizik:

o := ((Metaclass allInstances detect: [:c | c superclass = ProtoObject
class]) instVarNamed: #thisClass). 1. "number here to avoid printing".

Smalltalk allClasses select: [:c | o isKindOf: c] -> an
OrderedCollection(Behavior Class ClassDescription Object ProtoObject)

Smalltalk allClasses select: [:c | o class == c] -> an OrderedCollection()

It looks like a subclass of Class :-)
