No, because Exim is designed to run as a number of independent,
short-lived processes, with no master "control" process. (The daemon
process is not a control process; it is just a listener.)
There has been talk of somebody writing a "database cache daemon" that
would run continuously and handle connections to a variety of databases,
and keep cached data. If such a thing were written, Exim could
communicate with it using the ${socket feature. But it would have to be
well written so as not to be a bottleneck between the different Exim
processes that access it.
