I think this is unlikely to happen but if you insist I'll quote from my last email: I think Roland's patch from http://lists.research.att.com/pipermail/ast-developers/2013q2/002431.html is sufficient for now because long before we exhaust VA space we run out of patience to wait for the jobs to complete :) If that's not sufficient then I'll suggest the '44bit clamp' Roland proposed to partition 64bit VA space into 65536 files with 44bit chunks mapped simultaneously. That just leaves 16 times the same amount of memory for anon memory pages (which is many times the amount of world-wide installed main memory in 2012).
