here again.

hmm, why not shift ?

Because it makes reading code harder and because compiler
  is smart enough to choose appropriate instruction for
underling CPU architecture.

ok.

I think that xfer is too vague in this case, prefer write or send.

ok. Will change it to send.

static? please fix.
   That was intentional. Using to pack tag and data in to one word across
   two calls. So preserving val, idx across calls.

Sorry this is no go! Reorganize the code, please.

Ok, will change this function.
