Hi,

I have just build a Win32 VM using VMMaker3.7a and this changeset.
I tested the change in a 3.7a-5596 image.

It is definately a lot quicker.

I used Andreas's test:
   m := PasteUpMorph new.
   [1 to: 100000 do:[:i| copy := m clone. m copyFrom: copy]] timeToRun.

My results were

Without primitive:  6392 6404 6438 6417 6417 6401 6372 = avg 6406ms
With primitive:     74 73 73 73 73 74 75 73 69 = avg 3ms

The VM code changes look fine to my weary eye; I have absolutely no idea if
this will make a whole system snappier but it definately speeds this test
up.

Regards,

Brent
