Virtually everything just said is completely incorrect, but this takes the icing on the cake:
Why even bother to post?
How do you know that any low memory log was actually due to lack of RAM,
poor use of RAM, or not freeing it, or memory leak, without having the source
code for every app resident in the background and iOS Safari?
Every low memory crash I have witnessed was due to allocating, but not freeing RAM,
but the low memory warning is all that is logged.
