D6 documentation

> I think that the 'Thread Affinity' sub-section of:
>
>     http://www.object-arts.com/docs/tooverlapornottooverlap.htm
>
> is out of date and should be re-written.
>
> BTW, I think that the point of the first paragraph of the 'Unexpected
> Multi-processing' sub-section (of the same page) is that Dolphin,
> unlike some other Smalltalk implementations, does do pre-emptive
> mult-tasking amongst Processes of equal priority.  If so then I don't
> think that comes across very clearly.  OTOH, if that isn't the case,
> then that doesn't come across very clearly either ;-).
>
> Another BTW, on the 'Virtual Calls' page:
>
>
> http://www.object-arts.com/docs/virtualcalls_c___olecominterface_.htm
>
> it might be worth making it clear that you can't overlap virtual
> calls (unless that's now possible, of course).
