+Use `qemu_exit()` function instead of `exit()`
+Additional information:
+I just saw the similar refactoring for the GDB part of QEMU and thought it might be useful in more general case too: https://lore.kernel.org/qemu-devel/20230907112640.292104-1-chigot@adacore.com/T/#m540552946cfa960b34c4d76d2302324f5de8627f

+Performance degradation for WinXP boot time after b55f54bc
+
+Qemu 5.1 loads Windows XP in TCG mode 5-6 times slower (~2 minutes) than 4.2 (25 seconds), I git bisected it, and it appears that commit b55f54bc965607c45b5010a107a792ba333ba654 causes this issue. Probably similar to an older fixed bug https://bugs.launchpad.net/qemu/+bug/1672383
+
+Command line is trivial: qemu-system-x86_64 -nodefaults -vga std -m 4096M -hda WinXP.qcow2 -monitor stdio -snapshot
+
+The QEMU project is currently moving its bug tracking to another system.
+For this we need to know which bugs are still valid and which could be
+closed already. Thus we are setting the bug state to "Incomplete" now.
+
+If the bug has already been fixed in the latest upstream version of QEMU,
+then please close this ticket as "Fix released".
+
+If it is not fixed yet and you think that this bug report here is still
+valid, then you have two options:
+
+1) If you already have an account on gitlab.com, please open a new ticket
+for this problem in our new tracker here:
+
+    https://gitlab.com/qemu-project/qemu/-/issues
+
+and then close this ticket here on Launchpad (or let it expire auto-
+matically after 60 days). Please mention the URL of this bug ticket on
+Launchpad in the new ticket on GitLab.
+
+2) If you don't have an account on gitlab.com and don't intend to get
+one, but still would like to keep this ticket opened, then please switch
+the state back to "New" or "Confirmed" within the next 60 days (other-
+wise it will get closed as "Expired"). We will then eventually migrate
+the ticket automatically to the new system (but you won't be the reporter
+of the bug in the new system and thus you won't get notified on changes
+anymore).
+
+Thank you and sorry for the inconvenience.
+
+
+Ticket has been moved here (thanks, Maksim!):
+https://gitlab.com/qemu-project/qemu/-/issues/286
+Thus closing this one at Launchpad now.
