Description Michael Catanzaro 2024-09-19 14:05:50 PDT 
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.
