Well, we need to continue to support SM 1.7 on the 1.0.x branch, and if that means 1.0.x doesn't
work with SM 1.8.5 then so be it.  For 1.1.0 I'd want to know what the availability of SM
1.8.5 in various package repositories looks like before dropping support for SM 1.7. Ideally
I'd like to ship at least one version of CouchDB that works with both SM 1.7 and SM 1.8.5,
but I've seen Chris' work in COUCHDB-1078 and I don't relish the thought of making that any
more complicated than it already is.

Trunk can drop support for SM 1.7.
