Hi Andreas.
Talking about getting bitten... is finalization *supposed* to not
distinguish between objects that are #= but not #== ?
Finalization in 3.9a 6680 was completely broken (never did anything),
and in 3.8 (and maybe before) would hold one executor for every #=
equivalence class.
Assuming none of this is by design, test cases and fixes are in:
http://source.squeakfoundation.org/inbox/System-dvf.26.mcz
and
http://source.squeakfoundation.org/inbox/Collections-dvf.22.mcz
I'd like your opinions on those, I'm not particularly knowledgeable
about finalization. BTW, after the fix a WeakRegistry's Default should
be nilled out for proper reinitialization to take place.
