It came back. That code segment *does* seem kind of nasty, and does
seem to assume that "size_t" and "unsigned" have the same word length.
However, I can't say it bears any resemblance to "our" code.
The Net/OpenBSD relation is because of the *kernel* malloc. Someone with
the stature of Ilja should know that this is a fundamentally different
beast as the userland malloc, and that *no* userland malloc will ever
turn into a kernel malloc.
I think he just might've lost his edge.
