Harumph.  Yes, you're right about that.

I was thinking that a fork design would allow you to make
use of tar's deep directory support (which uses chdir() a
lot and would make passthrough mode pretty tricky).  But
the cpio design makes deep dir support tricky no matter what.

I still stand by one assertion above:  start with passthrough mode.  ;-)
