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.
In this sense, it would be more appropriate to use the terminology
"file-backed DB caching" / "shared memory DB caching" instead of "disk
caching" / "memory caching". - Jong
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?
