Current DirectoryIndex Map died hard when the database does't map filesystem layout

[phochste]

I have use case where I use the Map DirectoryIndex for the temporary storage of files which get cleaned up with a crontab scripts. When the file layout doesn't match directory mapping stored in the index, the DirectoryIndex will die.

Can this behavior made configuratble?

- default : die when filesystem in inconsistent
- optional: skip directories not found with a warning message
