Okay, interesting. I guess I've seen it before, so I didn't think it was Ruby-specific, but I also haven't had to do that kind of programming in a very super long time.

Publib then? I'm finding this when I search: http://man.cx/xfree(3) http://man.cx/publib(3)

Also, are you sure? I see xmalloc in glibc all over the internet...
