Please mind that WCAP currently caches (by default) the last 4 queries for 2 minutes to speed up toggling the views (aka in composite).
It's hard to judge on memory consumption and how much memory the js engine comsumes since garbage collection is non-deterministic. Looking at the WCAP code, I don't see an obvious leak.

Has there been any change in the way WCAP works in the latest 0.8pre nightlies?

(This bug should be resolved accordingly if this isn't a valid issue)

I think we should close this bug. As Daniel mentioned, garbage collection is non-deterministic. We have many other perf bugs that should increase performance. This might go to the cost of memory, but memory is cheap these days.
