Created attachment 38642 [details] Crashlog I haven't been able to figure out how to reproduce this beyond "browse normally with a WebKit nightly build for a while". The attached crashlog is representative, but it doesn't always crash. Sometimes it just spins up a ton of threads for a while, then quiets down again.

Created attachment 38700 [details] proposed fix I could never reproduce the crash, but this should greatly reduce strain on CFNetwork. Magic numbers used here are not special or tested in any way. I did try browsing with some additional logging, and both CFHost calls and network requests made seemed reasonable.
