We could say that C-g sets quit-flag and causes all blocking calls to
condition-wait to return nil (spurious wakeup). At that point all
threads are conceptually running. Then the first thread (unspecified
which one) who calls maybe_quit() finishes handling C-g and clears
quit-flag afterwards. Those threads who don't feel prepared to handle
C-g can bind inhibit-quit.
