Although Dean already has moved mod_mmap_static inside the Configuration to

change its priority, it doesn't hurt is when we are additionally be even more
conservative:

Let mod_mmap_static be more reserved unless at least one "mmapfile" directive
is present in the configuration. Because this experimental module has to do
some black magic to operate inside the current API and thus forces
side-effects for other modules under some circumstances.

PS: For Apache 2.0 we really need dynamically configurable
    priorities _per API hook_ for each module, yes....
