So why do you bother?

Well, the blob is nothing but datat in the file-system. If you are 
*really* concerned about that, then don't use the db, but use the 
filesystem, appending to the file until it's finished - and storing a 
reference to it to the DB. We do that as well, because otherwise the db 
will become unmanagable anyway (dumping, backups).

In theory, the DB might offer special stream-based methods for these 
kinds of tasks, but the db-api lacks them. Some DB-adapters might offer 
some non-standard-extensions, but I don't think sqlite does.
