Log message:
Account for in-flight pages being written to disk when computing page shortage.
Due to its asynchronous design, on MP machines, the page daemon was generally
over swapping memory resulting in a degenerative behavior when OOM.
To prevent swapping more pages than necessary, take the amount of in-flight
pages into account when calculating the page shortage.
