It was inconvenient that perf cannot be quit with SIGINT during processing samples on TUI especially for large data files. This was because the first argument of SLang_init_tty(), abort_char, being 0. The manual says it's the ascii value of the control character that will be used to generate the interrupt signal [1]. Passing -1 means to use the default value (Ctrl-C). However, after processing samples, Ctrl-C was used to in other cases as well - like stepping back from annotate. So recover the original behavior after processing.
