Yet, I'm told in IRC that the cache queue no longer exists.

Draft language, derived from an IRC discussion with debdrup several weeks ago:

"There are a couple of kinds of "free memory". One kind is the amount of memory immediately available without paging anything else out. That is approximately the size of the free queue + the combined size of the inactive and laundry queues (with a derating factor, depending upon system tuning), all as shown in &man.top.1;. Another kind of "free memory" is the total amount of VM space. That can be complex, but is dependent upon the amount of swap space and memory. Other kinds of "free memory" descriptions are also possible, but it is relatively useless to define these, but rather it is important to make sure that the paging rate is kept low, and to avoid running out of swap space."

Can someone who understands those things check my language for accuracy?
