            Bug ID: 170741
           Summary: webkitpy: Ignore previously launched pid when system
                    is under stress
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jbedard at apple.com
                CC: lforschler at apple.com

When launching apps on an iOS Simulator, xcrun simctl launch will sometimes return the pid of the previous process if that process is still being torn down.  When the system is stressed, the race conditions which exist here can get worse.  Mitigate these issues by checking if the returned PID is a new PID in SimulatorProcess.
