Just to clarify... 32MB would never ever be reached. The S/G table limit means requests are limited to 8MB. VM thresholds and user application use further limit request size. I think Andrew's point is actually more relevant than examining the size of a single request: > the effect of really big requests will be the same > as the effect of permitting _more_ requests. Thus like the "1,000 disks" example, memory management needs to make sure that an "unreasonable" amount of memory is not being pinned.
