 tried this too under HEAD (r205390):
 
 `gpart create -s gpt -n 1000000 /dev/da0` gave me "gpart: provider: No space
 left on device" so i did `gpart create -s gpt -n 1000000 /dev/da0` instead
 which worked. reattaching the device caused no problem.
 
 when i tried to create a label with `glabel label usb da0` i got:
 
 GEOM: da0: the secondary GPT table is corrupt or invalid.
 GEOM: da0: using the primary only -- recovery suggested.
 GEOM: da0: the secondary GPT table is corrupt or invalid.
 GEOM: da0: using the primary only -- recovery suggested.
 GEOM: label/usb: the secondary GPT table is corrupt or invalid.
 GEOM: label/usb: using the primary only -- recovery suggested.
 
 seems -n 1000000 is not enough to fill up kernel virtual memory in my case.
