Re: 2.1 & 2.2 statistics, and some odd behavior that needs to be examined.

The BDB environment (__db.*) is located on disk, rather than in memory.

With the shared memory BDB environment, the BDB memory pool resides in the shared memory, while with the file-backed memory mapping, the BDB memory pool is backed by files.

Okay, so now that we have the semantics nailed down...

Any thoughts on why 'file-backed DB caching' is causing such a problem under 2.2 as compared to 2.1?
