As ubuntuone is pretty much the only (important) rdepends of couchdb in oneiric now, it would not be an unnecessarily big risk to update it now. My main concerns here are the performance regression (which seems to be just a question of where to apply the workaround/fix you mentioned, in couchdb or in desktopcouch), and the mentioned crash. If such a crash didn't happen with the current version, that does seem to be a reason for investigating and fixing it first before upgrading?
Is there anything else except for the cherrypicked fix for #780972 which you need for oneiric? If so, I'm fine with going 1.1 if the crash gets fixed, otherwise a cherrypick sounds appropriate at this time.
