Hi Jared,
It's true, array_walk_recursive() used the php_array_walk() and it can cause
some serious problem within the stack.
The way to fix this bug is to prevent the "out-of stack limit". I'll send a
patch if i can find a way to fix correctly this bug.

The problem is that setrlimit() need privilege to expand the
process stack.
I don't think it's a good idea to use this system call to fix
the too-high-function-stack bug.
There is no really way to fix correctly this bug.
However I think we should re-examined the execution flow of
PECL functions.
How about core functions too.. Using array_walk_recursive to undo
magic_quotes creates a stack smashing exploit.
