If I comment out the assertion in ResourceHandle::setDefersLoading(bool), another assertion failure is observed later after click the button on test page several times.

Following is the trace log,

ASSERTION FAILED: m_suspended
../../../Source/WebCore/page/SuspendableTimer.cpp(76) : virtual void WebCore::SuspendableTimer::resume()

Program received signal SIGSEGV, Segmentation fault.
