Subject: Turn ArduControl command_queue into a Task
X-Git-Url: http://git.tdb.fi/?p=r2c2.git;a=commitdiff_plain;h=aa48746158b19ad795a3cc656c4dfe17044baf54

Turn ArduControl command_queue into a Task

It seems that I was thinking of this back in d5d8ee8, but left it
unfinished probably because it was simpler to use a Queue directly.  Now
some upcoming task management improvements call for it to be a Task.
