           Summary: CoreIPC ommits some messages when sending a lot of
                    messages in a very short time.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: seulgikim at company100.net


I observed CoordinatedLayerTreeHostProxy::CreateCompositingLayer message are sent but not received when a lot of messages are sent in a short time.
I tested http://black.company100.net/test/TC/leaves1000 (this site creates 1000 compositing layers) and checked that CoordinatedLayerTreeHost actually sends all messages but CoordinatedLayerTreeHostProxy doesn't receive some messages.
This test page sends 1000 messages almost simultaneously.
CoordinatedLayerTree in EFL and Qt had the same results, so I assume CoreIPC in unix has problems.
