> It looks like the FileDataStore garbage collection (both regular scan and 
> persistence manager scan) can delete files that are still needed.
> Currently it looks like the reason is the last access time resolution of the 
> operating system. This is 2 seconds for FAT and Mac OS X, NTFS 100 ns, and 1 
> second for other file systems. That means file that are scanned at the very 
> beginning are sometimes deleted, because they have a later last modified time 
> then when the scan was started.
