It's possible that the cursor does not reappear after pressing ^C during
shutdown. In my case, I noticed this when pressing ^C after getting
results from `pacman -F` -- this can reasonably reliably be triggered by
issuing a file query and pressing ^C shortly after results are shown.

There are two reasons for this issue:

1. The graceful SIGINT handler is removed at the start of cleanup(), but
   the window from entering cleanup() to reaching exit() is non trivial.
   The main offender is FREELIST(pm_targets), which on my T14s takes
   >0.1s to execute. This means that if you are unlucky enough to press
   ^C while there, the cursor isn't coming back, because we haven't
   issued any command to show the cursor again yet, and the userspace
   signal handler is already blown away.
2. Moving console_cursor_show() to earlier in cleanup() only half solves
   the issue. While it's fine not to flush after _hiding_ the cursor,
