Removal Attempt of Directory under ZFS causes Kernel Panic

[Martin McCormick]

	You will see a message on this group from Ryan Frederick
who is a coworker of mine and who also posted a question about
this same issue. There was a little confusion about which
FreeBSD support group had been asked so my question and his are
about the same machine. He submitted the stack trace so
hopefully somebody can give us an idea as to how this happened.

	Thank you again.
