Yes[0], yes, yes.


[0] someone reported SQLite connection timeouts during seeding with high concurrency, but he didn't report any further numbers. I do think this might happen when IO load is very high, but in this case you should reduce concurrency to a more moderate value. More feedback is welcome.
