Steps to a spoony VM

Hi Tony--

      Yeah, looks like I left in a "3 halt" by mistake in 
Interpreter>>primitiveFail, which of course gets sent by a lot of other 
places. There's also a halt I was using during simulation in 
LargeIntegersPlugin>>noteMissingPrimitive:, which you noticed after 
translation to C (it should be removed before translation).

 >  - the call to cleanUpContexts [in
 > Interpreter>>primitiveSnapshotWithoutStaleMethods]

      That's a vestigial thing from 3.2 that I didn't catch, that line 
should just be removed.

      That happened because of the halt in LargeIntegersPlugin mentioned 
above, I assume.

      Thanks for going through the building process, and for taking notes!
