!!8x takes about 6s to run on my machine so you can see that this
prints dots without a newline and without getting cached. This works
interactively and when piped to a file (1!:2 will also seem to work
interactively, but won't be as kind to piped output). Depending on what
you're doing it might be better to write to /proc/self/fd/2 (stderr).
You can also make the writes conditional on isatty 1 (or 2 if you're
writing to that), so that you don't get this kind of human-oriented
output when a human isn't looking. An isatty conditional would
incidentally suppress this output in JQt, where you'd just get an
interface error from it otherwise.
