AIUI, moving from mythbackend generating previews to mythbackend
generating previews in a separate process was hard.  Moving all the code
from mythbackend that's involved in generating previews to a whole new
binary /and/ making it work well in mythbackend and mythfrontend and
everywhere else it's used was so much harder that it wasn't (yet) worth
the effort.

I can pretty much guarantee that the total amount of time people will
spend fixing their monitoring scripts (even when duplicating work) is
significantly less than the time it would take to rearrange things
"properly."
