Comment on attachment 345128 [details] Fixed non-iOS builds View in context: https://bugs.webkit.org/attachment.cgi?id=345128&action=review > Source/WebCore/ChangeLog:8 > + Turn this into a debug assertion in WebKit1. This needs more explanation that mentions the JSC lack of WebThreadLock etc, and reference a radar.
