I've found a 100% repeatable way to panic the kernel under at least the i386 port.
I discovered this by accident last night by mistyping, but it have been able to
reproduce it under the GENERIC kernel with nothing wierd going.

Typing:
	mount <directory> <directory>
where both instances of <directory> are the same filename causes a panic
with the error message 'panic: locking against myself'.  Is this a known
bug, and has it been addressed in -current?
