I've found a remark regarding write concurrency in SQLite:

"All SQLite write operations obtain an exclusive lock on the whole database"
( http://www.mail-archive.com/sqlite-users@sqlite.org/msg18342.html )

Doesn't it mean, that database is protected enough already by it's internal
design, and there's no need to take care about that "dot locks"?
