[PATCH] Convert other drivers to use WrapperNode.

It still looks like mach-o files are parsed immediately (not in parallel).  If that is intentional, because reworking the mach-o logic is complicated, then leave a FIXME comment there.

It would be helpful to rename parseFile() if its goal is no longer to parse files.  I seems like its goal is to load the file into memory, and later parse()/doParse() are supposed to do the actual parsing.
