            Bug ID: 199857
           Summary: [WTF] Thread::removeFromThreadGroup leaks weak
                    pointers.
           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: Takashi.Komori at sony.com

ThreadGroup's destructor calls Thread::removeFromThreadGroup and tries to remove its weak pointer from Thread.m_threadGroups.
As the call is from destructor the instance of ThreadGroup is already released and the removing always fail.

As a result, the size of m_thraeadGroups won't decrease.
