Comment (by Peter Bennett):

 I ran a test with a full xmltv download, 729 channels for 2 weeks, in
 master.

 Current master version
 {{{
 virt / res
 7 GB / 5.62 GB
 22 mins
 }}}

 With patch
 {{{
 virt / res
 2 GB / 689 MB
 17 mins
 }}}
 The patch reduced the resident memory requirement from 5.62 GB to 689 MB,
 a factor of 8. Also it reduced the run time slightly.

 With the patch, all listings look correct. It also added channels and
 channel icons, as expected.
