There is of course another option, which is the issue was caused by another factor entirely. Running out of RAM isn't hard to do, and i think you'd find many who have done so (myself included, many times). So presuming the claim is correct as documented i have not reproduced this, but since his proposition is trivial to test why don't you experiment for yourself, post your findings and test code back here when you have.
I think it will set your mind at ease.
