Well, some very old libraries will SIGSEGV on free(NULL). Admittedly those libraries are either very old or _very_ broken, but if you want to be strictly portable, you should not ever pass NULL to free(), unless you actually got it from a malloc(0) (and even then, it might be a really broken libc that just ran out of memory). I actually suspect we should wrap all free() calls as "xfree()", which may also help us some day if we want to do any memory usage statistics.
