Personally, I alway suggest to apply the currently available patches, and
I always deploy patched versions of slapd with db-4.2.52, but I wouldn't
agree with __requiring__ BerkeleyDB to be patched for a number of reasons,
including the fact that the patch actually isn't official, so customers
might prefer to live with an official db-4.2.52 as far as they're aware of
the limitations it implies.  In fact, we can surely live without that
patch, provided we periodically shut the service down.  In this case a
stock db-4.2.52 would perfectly fit every need without any patch.

I strongl agree with slapd trying to detect at compile/run-time if the
db-4.2.52 is pched or not, and with logging the result.  We could have the
behavior you envisaged as the default (i.e. slapd refusing to run with a
non-patched db-4.2.52), with a switch that allows the conscious admin to
work it around (i.e. some "live-with-unpatched-db" config parameter).
