It would be hard to do it in the appserver, though there are always
ways, but doing it in the buildd-manager seems possible.  I guess by
specifying dotted revnos and so on you can make generating the manifest
fairly expensive and so risk slowing things down... but not much more
than everything else in this system (I mean OO.org is almost DoS in
itself :-p)
