Ah yes, thanks for that - it should be relatively easy to add back in the 
Go code to support all architectures (it was all originally Go before 
rewriting in ASM for the SIMD) so I'll add a note to do that soonish.  The 
SSE4 requirement may be able to be relaxed too as the traversal code 
doesn't use anything > SSE2 so I'll look into it at some point.
