My projects could really benefit from using the SQLITE_FCNTL_CHUNK_SIZE file control operation to override the default file allocation chunk size to make sqlite allocate larger chunks and potentially avoid some file fragmentation (not table fragmentation, of course).
I experimented by using some reflection to get SQLiteConnection._sql and subsequently invoke FileControl, specifying SQLITE_FCNTL_CHUNK_SIZE with a 4MB chunk size, which in my test recreating the same ~120MB test database brought down the NTFS fragmentation of the resulting file from about 1000 fragments to 6-7 fragments.

I'd therefore like some way (connection string and/or method/property on SQLiteConnection) to specify the chunk size.

Fixed on trunk via check-in [146cb55f1e].
