After years of this bothering me I have decided it's likely a javascript problem. Specifically: if I visit a page with lots of js perhaps it loads something into OW which can't unload it when the page is no longer around. Thus restarting, which doesn't load the offending page, is a "cold boot" GC.

It could be some other plug-in (flash sucks pretty hard too). The reason I think it's JS is that I mostly have JS disabled except for certain pages. It seems to happen when I have visited those pages.

But I don't know the internal architecture of OW so this is a black-box analysis. So don't treat it as any kind of massively-researched gospel!!
