            Bug ID: 280014
           Summary: REGRESSION(247615 at main): [WPE][GTK] Suspended cached
                    web processes remain forever after UI process
                    terminates uncleanly
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at redhat.com

Splitting this out of bug #279913:

 * Run Epiphany or MiniBrowser in a terminal
 * Open a tab and close it, wait until the web process cache suspends the corresponding web process
 * Ctrl+C

Notice the web process remains in suspended state forever. Its only mechanism to quit itself is to receive a HUP event on its IPC connection to the UI process, but that cannot happen because it is suspended. Only the UI process can unsuspend it, but the UI process is gone. We would need a new process monitor auxiliary process to fix this.
