4	use SSE2 to speed up multiplication	zooko	somebody	"Jack Lloyd contributed a patch that speeds up encoding using SSE2 instructions (on some platforms).  Unfortunately there is this mysterious problem where it actually causes it to slow down when it is executed from Python!  So this patch probably shouldn't be applied as-is, but someone should investigate and figure out why it causes a slowdown when invoked from Python but not from C.
