From 6732ce6edcf1562d3e126ed02f96466ab07c498e Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 00:40:03 -0300 Subject: A desktop session holds 64 panes, and every route that finds none free says so Sixteen panes was far too few for a real session. MAX_PANES is now 64 on a desktop and stays 16 on the board; the 48 more slots cost about 3.7 KB each in fixed tables (the core 1.33 to 1.45 MB, its surface 19 to 72 KB), and a pane itself (84 KB and its terminal) is allocated only when it opens. At the cap, pane/new fails with `pane/new: no pane slots: 64 max` and an err record rather than a bare ENFILE, a 9P look or exec that would open a pane fails its write with the same words and reads back empty, and New, Tty, Tutor and Alt-n say it on the message row (their ctl writes fail with it).
