            Bug ID: 173975
           Summary: WTF::Thread should have the threads stack bounds.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: keith_miller at apple.com

There are a number of places in JSC that try to walk another threads stack. Currently, the stack bounds are stored on ThreadData but that's in TLS so other threads cannot see it. Right now we get the stack bounds by iterating the MachineThreads looking for our target thread then getting it's stack bounds. We should just put the stack bounds on the Thread.
