The shortened transmit gag was written for an Ultrabeam that is now polled
four times a second while it moves. The SteppIR was still on two seconds
and reported nothing at all until its own poll came round, so the gap
between the 900 ms grace and the first poll that would have seen the
movement was a hole in "block TX while the elements travel" — the
transmitter released in the middle of a move.
It now reports a commanded move at once (bounded, so an antenna that
never answers cannot latch the inhibit on), on a COPY of the cached
status so the flag cannot leak into what the poll goroutine owns, and
follows the motors with its poll rate exactly as the Ultrabeam does.
