 Description   

This statement in the current prouction notes is incorrect: "The WiredTiger storage engine also ensures that the operating system does not store MongoDB data in swap space."

We make no such guarantee: data stored in WiredTiger may be stored in swap space if there is sufficient memory pressure.

Further, the statements "The MMAPv1 storage engine is not CPU bound..." and "The WiredTiger storage engine is CPU bound" are misleading.

I think the intent is to say "the MMAPv1 storage engine does not require many CPU cores" and "the WiredTiger storage engine is multithreaded and may require (can take advantage of) many CPU cores".
