As it turned out, I rewrote the bcache so it works better. I haven't
heard back from HP on this, but I suspect its overhead is now low
enough that they wouldn't have noticed it to begin with. So, as
symtab maintainer, hpjyg09 is now dead, until I hear an explanation of
why the changes to the bcache were insufficient.
