Subject: [PATCH] Raise the default VMThreshold from 1Mb to 8Mb

This seems like a fair change based on modern hardware and, in particular

modern PDF files. In some cases this results in a significant speed

improvement. It may increase overall memory usage, but testing suggests only

by an insignificant amount in the vast majority of cases.

No cluster differences.
