 2# Regression test for the `zmx kill X; zmx run X` race.
 3#
 4# Previously `zmx kill` returned immediately after sending the IPC .Kill,
 5# while the daemon's shutdown defer ran handleKill() -- SIGHUP, 500ms sleep,
 6# SIGKILL -- BEFORE closing/unlinking the listen socket. A `zmx run X`
 7# issued in that window would connect() into the kernel backlog of a
 8# socket the daemon would never accept() on again, then get RST'd
 9# (ConnectionResetByPeer) when the daemon finally closed the listen fd,
10# exiting 1 with no output and no session created.
