Gah! You hit this one right on the head. I thought I had equivalent
mtx_destroy calls for every mtx_init, but there's a section of code that
bzero()s a structure containing a mutex before initializing that mutex,
so that caused this common mutex to be initialized twice without
triggering a panic in witness_init(). The subsequent destroy only
removed the one instance.
I've fixed said code and now I can load/unload to my little heart's
content. :).
Thanks for replying.
