Comment (by adamsilverstein):

 in [attachment:34560.5.diff] :
 * cleanup patch

 memory use now down to ~6.3MB (!!!), the revisions are no longer causing
 high memory consumption on the post edit page.

 before:

 Note: the issue is most notable when there are many large revisions,
 however it is present on much smaller data sizes as well.
