It can be fixed by moving the binding to undeclared in #removeFromSystem:
This is done by adding
Undeclared declare: self name asSymbol from: Smalltalk globals.
before the "forgetClass: self logged:" line.
What we need to do in addition: Only do that when the class is referenced.
#isUsedClass: does that, but it does integrate over all methods in the system.
(I sometimes wonder if we should not late-bind accesses to globals, that is,
just compile them as message sends to the environment).
