Intentional deviation from Ghostty 1.3.1 (DEVIANT_FIXES.md row 37).
On shutdown Zig's termio/Exec.zig:1188-1224 (getpgid) loops until the
child's process group differs from ours, i.e. until the child has
called setsid. If the child exits before ever calling setsid and is not
yet reaped, its pgid stays ours forever and Zig spins indefinitely.
The Rust port previously capped the wait at ~5 s (which also differed
from Zig for slow children). It now waits without a cap like Zig, but
stops as soon as waitid(WNOWAIT) shows the child has exited.
Test Plan:
- cargo test -p ghostty-termio getpgid_waits_for_late_setsid
getpgid_gives_up_on_exited_child_without_setsid
