Interbase 4/Linux used to spawn a lock manager, so there is
surely some locking going on. Also I assume you'll need some
locks e.g. to protect the data structures in a shared cache
(I'm not even thinking about transaction locks, but more about
basic things like linking buffers in a free list etc.).
