--- Comment #1 from Michael Catanzaro <mcatanzaro at igalia.com> ---
I guess there are two likely possibilities here:

 * urxvt is probably the controlling process of the session that WebKit is running in, so when it dies the kernel is going to send SIGHUP to all processes in the foreground process group of its controlling terminal.

 * Alternatively, maybe more likely urxvt's death could have caused the process group of the WebKitWebProcess to become orphaned; that will trigger a SIGHUP.

Either way, it wouldn't be a WebKit bug. I'm going to close this because I really doubt there is a WebKit bug here. For a better understanding of terminal job control, you might want to investigate chapter 34 of "The Linux Programming Interface".

The only part I don't understand is why the UI process does not die too!
