In *some cases* where you need to keep a local list of things to free,
you can deal with this by keeping the list on-stack.  At Andy's suggestion,
that's what we did in one or two places in the opencrypto code.  I don't
know if it will work for what you're doing but I thought it was worth
mentioning just as a general technique.
