Useful4 Signal2
Quitting no longer hangs; Claude Code force-kills itself and also handles hangup signals.
What's wrong with this entry?
Anonymous. No account, no email.
What
If the normal exit fails, Claude Code now kills its own process outright rather than sitting there. Shutdown also handles SIGHUP alongside SIGINT and SIGTERM, the UI teardown resolves or rejects the exit promise so anything waiting on it is released, and pending events are flushed before the internal event channel closes.
Evidence
process.kill(process.pid, "SIGKILL")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
