The latency I was worried about was round trip time - if we have to
request a half-dozen out of a hundred registers, then this will
probably take longer than a whole g packet would, because of waiting
for each side to process the conversation. I guess we'll ignore it for
now and investigate smaller regsets later with qPart.
