That was what I said at first too, but then I realized that if you have 
myth running in the mode where it closes the dvb device when not in use, 
you have exactly the same situation -- the dvb frontend is closed, and 
thus other applications can mess with it in the interim. I would hate to 
see the motor have to assume it's starting from timbuktu every time the 
dvb device was re-opened. And as long as I'm putting that sort of 
functionality in, I figure it might as well be persistent, on the theory 
that it's much more likely that the assumption that the motor hasn't 
been changed since the last backend run is way more likely than the 
assumption that the motor has, and anyway the result of assuming that 
the motor hasn't been externally changed isn't any different than what 
we have now -- the motor command would still be issued, and the motor 
would eventually get to the right place, but the percent complete 
indicator wouldn't be accurate in this (probably unlikely) case.
