Not sure SQLLite is the best of the SQL's for 'sidestepping' the issue where
writes may be involved. ISTR it works against a file and has rather basic or
'coarse grained' access locking.
Not a problem with massively parallel *reads*, but might one not get into
contention issues with writes?
Thinking other Exim child processes also trying to write.
