Here is the key part of a trace-malloc snapshot with 1.4GB allocated. Almost all of the memory is created through nsXMLHttpRequest::ConvertBodyToText, which I believe is called to access the property |requestText|.

What I don't understand is why the nsAStrings returned by ConvertBodyToText are not freed in XPCWrappedNative::CallMethod after the call. Who would know about this?
