How common is spamd/spamc?  If almost all SpamAssassin installations
that use dccproc but ought to use dccifd also use spamd, then the code
in dccproc that starts dccifd will be a useless waste.

I wonder how many installations think they are using dccifd but
because they start spamd before dccifd are in fact using dccproc.
