For the times when it does not cause a panic, does it cause any
other problems? Ie, would it be better to say "procedure is
pretty dangerous *because* it sometimes causes a panic"? Or
is there some other problem in addition to the possible panic?

What kind of hardware are you doing this on? Is it multi-CPU?
Does it have a lot of RAM? (I am just curious...)
Once you have a dump, you might want to include
Kirk McKusick <mckusick@beastie.mckusick.com>
on a message with a pointer to the dump. I don't know how
often he reads freebsd-current.
