So this is really an over-release, not balanced with a retain? Perhaps there could be separate controller objects for the web views, which stay around (having trivial retain, release, etc), being reused when they become available. So there will be at most FVWebIconMaximumNumberOfWebViews of those, not just at one time but over the whole run. That would give an upper bound to the leak. They could perhaps also keep their respective web views, which would give some speed improvement, but at the cost of memory and perhaps interference between icons. > The bug seemed to happen even before Apple disabled non-https loads, so maybe > it's something that happens with any failed load.
