[PATCH v2] ui/cocoa: Do not exit immediately after shutdown


From: Akihiko Odaki
Subject: [PATCH v2] ui/cocoa: Do not exit immediately after shutdown
Date: Fri, 19 Feb 2021 20:16:52 +0900

ui/cocoa used to call exit immediately after calling
qemu_system_shutdown_request, which prevents QEMU from actually
perfoming system shutdown. Just sleep forever, and wait QEMU to call
exit and kill the Cocoa thread.
