The proc bug exhibits only under heavy load. I've never looked at the
internals, so I don't know if these arrays could be the cause of the
crash but I will cheerfully test it if you send me the patch. I some
have easily reproducable test cases.
(discl: I can't speak to if the patch gets accepted in the end)
