No, they don't.  Integer arithmetic can be parallelized much more
thoroughly.  But when we are working with a byte-code interpreter, the
parallelization will speed up the byte code interpreter itself, but
hardly the arithmetic fed into it: the interpreter will not issue
arithmetic fast enough to make a difference.
