From 8d93016e923565e2e8b73aa7b549dd65b5d18a8c Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 15:02:31 -0300 Subject: Kill signals a command only while it runs, and only the pane it was meant for A signal effect carried only a slot, so a Kill followed in the same step by the pane's closing and its slot's reuse signalled the new pane's child; and a command pane whose child had exited and been reaped kept a process group id another process could take. The effect now carries the pane's serial, checked as it is performed, and a host signals no command whose exit it has recorded; the core already sends Kill only to a command it has not been told is done.
