Excessive memory usage by unity-webapps-context-daemon

unity-webapps-context-daemon uses way too much memory for an application that simply gives me an icon to click on to get to a web application. This can be done with zero memory usage with a revolutionary technology called a "bookmark." For example, Facebook is currently using 80M RES / 473M VIRT:
/usr/lib/libunity-webapps/unity-webapps-context-daemon facebook facebook.com icon://unity-webapps-facebook [Invalid UTF-8]

I've seen it get as high as 120M RES before. This is crazy! Combine that with Google+, using 25M, Google Calendar with 15M, another 15M for Lauchpad, and Gmail with an unexpectedly low 6M, and another 3M for the unity-webapps-service, and we reach an appalling 141M RES memory being used. I really want Webapps to be useful, but until this memory situation is resolved, it makes no sense for me (or anyone else) to leave it enabled sucking up memory when the only functionality they give is that of some fancy bookmarks.
