--- Comment #3 from Mark Johnston <markj at FreeBSD.org> ---
Yes, I believe this is basically "works as intended".  It's a problem with the
aliasing mechanism in GEOM which allows one to refer to a device by multiple
names (/dev/da1pN, /dev/gpt/foo, /dev/ufs/bar, /dev/diskid/baz, etc.).  Once
something opens a device by one of the names, it obtains exclusive access to
the underlying device and causes the aliases to wither away.

My understanding is that the aliasing code has been reworked in head to avoid
this problem, but I'm not completely certain.
