anon_vma accumulating for certain load still not addressed

Hi, back in 2012 [1] there was a discussion about a forking load which accumulates anon_vmas. There was a trivial test case which triggers this and can potentially deplete the memory by local user. We have a report for an older enterprise distribution where nsd is suffering from this issue most
