# SIGWINCH crash (reported as "crash on font-size change"): resizing the outer
# terminal delivers SIGWINCH, and vaxis's default handler locks std.Io mutexes
# from signal context — landing on a thread inside an Io.Threaded syscall
# region (pty readers in read(2), main parked in queue.pop) panicked the Io
# machinery and killed pardes. Now every thread blocks SIGWINCH and a sigwait
# watcher consumes it. The in-pane kill storm below crashed pardes before the
# fix; the resize after proves the watcher still reflows the grid.
