I agree it seems to belong more in SmalltalkImage current than Smalltalk . TBH, I wouldn't mind if we split off a SmalltalkVM class as well :) I'm wondering about the comment in vmParameterAt: though, which states 40 is "VM word size - 4 or 8 (read only)" 1) Jannik provided a wordSize: method for setting... Does this work? 2) In Interpreter >> primitiveVMParameter, the comment reads "40 BytesPerWord for this image" I'd recon the VM comment is the correct one, and this is dependant on the image and not the VM, seeing as how it returns 4 for a 32bit image on the 64bit VM. In which case, I definately feel wordSize semantically belongs to SmalltalkImage (and thus should be cached there rather than SystemDictionary) ;) Cheers, Henry On Dec 17, 2009, at 8:44 46AM, StÃ©phane Ducasse wrote: >> excellent >> can you sync with marcus? >> We will have to clean SystemDictionary because this is not a namespace but a kind of clean trash.

It is always easy to say that. In addition, for Windows-only bugs we are very limited. Seems few pharo people use windows, or at least that are active in the community.
