           Summary: [EFL][WK2] WorkQueue::dispatchAfterDelay() doesn't
                    work properly.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit EFL
        AssignedTo: webkit-unassigned at lists.webkit.org

Sometimes, when UI Process is crashed, watchdocCallback() function in the ChildProcess.cpp doesn't triggered.
And found that, WorkQueue::dispatchAfterDelay() function uses ecore timer for getting timer event.

Ecore timer event will be processed by the ecore main loop,
and ecore main loop is in the main run loop, not in the WorkQueue thread.

When the UI Process is crashed, and WebProcess's ecore main loop is very busy or lockup also,
watchdogCallback() should be called to terminate WebProcess itself.
But WorkQueu::dispatchAfterDelay() uses ecore timer for timer event,
the watchdoc also cannot be trigerred.

The way to get timer event should be changed to use some other way like timerfd.
