            Bug ID: 199995
           Summary: WebKit spawns too many WebKitSharedMemory descriptors
                    under some circumstances
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bodqhrohro at gmail.com

According to ipcs -p, all these descriptors are shared with Xorg process. In Epiphany they may stack up to tens during usage, and in LuaKit, when resizing a window, I manage to have HUNDREDS of simultaneously opened descriptors. What are they needed for? Isn't it enough to use only 2–3 buffers for exchanging the graphics?

This also happens under Wayland, though the memory segments don't show up in ipcs -p, only in /proc/<pid>/fd/.
