Instead, let the child process terminate cleanly. The idea here is to match the behavior of unsandboxed WebKit and flatpaked WebKit and reduce the odds of bugs going unnoticed. This will allow exit handlers to run; notably, EGL termination has historically been a source of crashes. This will also avoid subverting the purpose of the watchdog thread that crashes the web process 10 seconds after the UI process exits. 2041364 1 mcatanzaro 2024-06-14 08:49:55 -0700 Pull request: https://github.com/WebKit/WebKit/pull/29825 2041583 2 ews-feeder 2024-06-16 05:43:57 -0700 Committed 280061@main (5d324a1c159c): <https://commits.webkit.org/280061@main> Reviewed commits have been landed.

I didn't actually test to ensure the web process would actually shut down cleanly. 2043993 4 mcatanzaro 2024-07-01 10:19:32 -0700 Sorry, I misunderstood. Carlos is saying it works for GTK but not for WPE. That seems extremely strange, though.
