Please try to read and understand the patches, before imagining that they might not be enough.
The active file list is kept at least as large as the inactive file list. Your backup is one large streaming IO. This means the files touched by your backup should go onto the inactive file list and get reclaimed, without putting pressure on the active file list.
If you are still not convinced that these (small) changes are enough, please test the patches and show us the results, so we can tweak things further.
