This is the code responsible for deleting the cookies:

<http://mxr.mozilla.org/mozilla-central/source/browser/base/content/sanitize.js#134>

For the case of deleting everything, it simply calls nsICookieManager::RemoveAll, which boils down to: <http://mxr.mozilla.org/mozilla-central/source/netwerk/cookie/src/nsCookieService.cpp#862>.

This code looks pretty sane to me.

The thing I'm not sure about is whether your test actually represents the cookie service's db queries precisely. Dan can probably comment on that.
