            Bug ID: 203873
           Summary: WTF::RunLoop should not depend on isMainThread()
                    idiom.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

The isMainThread() idiom is only meaningful for WebCore.  It is less meaningful for JSC since a VM instance can be entered from multiple threads, as long as only one thread enters it at any time.  Hence, the concept of a main thread doesn't make sense at the JSC level.

Since r251036, we started using a WTF::String to represent the RunLoop mode.  This caused problems for JSC clients when USE(CF) since it necessitated the use of StringWrapperCFAllocator to track the life cycle of the CFStringRef generated from the WTF::String.

To fix this problem, we should restore the original behavior of using CFStringRefs as the RunLoop mode token.
