As part of tokenization for (de)parsing, we need to do something like a disassembly, but is is really a little different. Disassembly, strictly speaking, is done by the xdis module now. What "ingestion" does is massage the instruction tokens to a form that is more amenable for parsing. In sum, ingestion is different than disassembly, although disassembly is generally the first part of ingestion.
