           Summary: [NRWT] the XvfbDriver should chose the next free
                    display
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kkristof at inf.u-szeged.hu


Now the XfvbDriver chose the next display id with these simple way:

running_displays = len(Executive().running_pids(x_filter)) 
display_id = self._worker_number * 2 + running_displays

But if we ran some parallel nrwt's they could choose an already existing display which can cause problems.
