OK, since we use memcpy rather than memmove in Squeak VM, I
implemented the trivial work around - move through a motionBuffer
temporary copy.

I now have a single test failing,
XTCollectionWriteStream>>#testReadWriteLargeAmount and this must be
due to my #after:do: simplistic implementation.
Messing with #fork in SUnit TestCase is tricky, and I need help on this point.
