Partition document storage on filesystem
There has been concern that ALL xml documents and revisions are saved into a single directory on the filesystem. There is a practical limit to the number of files any one directory can support (though I feel like we don't have definitive numbers on what those limits are exactly).
It would be wise if we could distribute our document/data storage across multiple directories. We could break the file name into subdirectory pieces, or do something more random. Suggestions appreciated.
