# DF-0589 run: load netgraph7 modules + run the race PoC
# Run as root on the DragonFly guest.
# Note: this pty-based PoC exercises the FORCE_WRITER-protected paths.
# The actual race (siopoll → l_start → ng_h4_start vs IF_DRAIN) requires
# a real sio serial port, which conflicts with the console on this guest.
