From 90f5c414a90afec978c8c0add58fd2a7e29acbaa Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 02:21:57 -0300 Subject: A read on a closed pane's event ends ENOENT, and the pane cap is ENOSPC 9ns reads an error's words, not its errno: "window shut down" came out as EIO where every other file of a gone pane gives ENOENT, and "no pane slots" as EIO. The event and pty/data reads a pane closed under now say "no such pane: its window shut" (ENOENT), and the cap says "no space for a pane: 64 max" (ENOSPC; 9ns has no word for ENFILE).
