[GLIB] WebProcess critical assertion during D-Bus RequestName completion on
process shutdown
https://bugs.webkit.org/show_bug.cgi?id=309693
Reviewed by Claudio Saavedra.
While rare, there's a chance that the WebProcess exits while the
AccessibilityAtspi dbus name callbacks are still in flight. If we don't
close them gracefully, we risk critical errors when the reply arrives.
This is likely related to 284894@main, which added the support for
well-known bus name to AccessibilityAtspi.
This happens, for example, in some WebDriver tests that quickly open and
close browsing contexts. A run with release asserts is reporting almost
30 crashes.
This commit addresses this issue by adding a graceful cleanup path to
AccessibilityAtspi.
