DragonFly dfbsd 6.5-DEVELOPMENT DragonFly 6.5-DEVELOPMENT #0: Thu Jul  2 06:02:54 UTC 2026     root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
hw.ncpu=6 (QEMU/KVM)
vkbd.ko loaded via kldload; /dev/vkbdctl alias present; /dev/kbdmuxctl absent (no kbdmux keyboard attached; syscons keyboard is kbd0 at atkbd0)
note: this boot had already seen ~116,699 clone units consumed by earlier open/write/close hammering (vkbd_wedge), which is why the 1000-cycle probe lands at 117699 rather than ~1000 — both numbers evidence the same leak.
