            Bug ID: 231304
           Summary: Add a configurable wake up message hysteresis to
                    IPC::StreamClientConnection
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org

Make it possible to avoid sending the wakeup message in StreamClientConnection, until some configurable number of messages have been queued up. This allows us to avoid triggering excessive wakeups in the GPU Process when using streaming IPC for display lists in the Canvas Lines subtest in MotionMark, which exercises sending a massive, constant stream of cheap drawing commands to the GPUP.
