Comment (by Peter Bennett):

 I ran a bunch of tests on the latest patch and everything looks good.

 With a valid file, it still performs as described above, using 698 MB
 instead of 5.6 GB.

 Changing one closing tag in the file results in an error termination with
 a good message about an unterminated tag, and no database update.

 Removing the final </tv> tag gives the same result, an error message with
 no database update.

 Adding extra tags (validly formatted), results in a successful load with
 those tags ignored (as I would expect). The same result is obtained with
 the current master version.

 Deleting complete tags from the file also results in a valid load with
 those fields not loaded (as expected).  The same result is obtained with
 the current master version.

 As far as I can see, the program performs exactly as current master, but
 uses only 12% of the memory. I recommend committing the changes.
