In its infinite wisdom, by default, SLang sets susp undef, and this can only be un-done by calling SLtty_set_suspend_state(true). After every SLang_init_tty(). Additionally, no provisions are made for maintaining the teletype attributes across suspend/continue (outside of curses emulation mode(?!), which provides full support, naturally), so we need to save and restore the flags ourselves, as well as reset the text colours when going under. We need to also re-draw the screen, and raising SIGWINCH, shockingly, Just Works. The correct solution would be to Not Use SLang, but as a stop-gap, this makes TUI 'perf report' usable.
