Be consistent!

Uniformity is best.

Switch to a better approach to integrating the main loop.
This will support testing for readiness before needlessly running a kernel call.

Beginning support for recursive SDWB.

These will work much nicer in hardware.

test for memory leaks
test tcp or udp

Prepare to test also sub-word accesses.

This allows us to provide sub-word bus access.

Try all permutations.
