Jordan K. Hubbard 1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

NAME
xmalloc() - get memory or bust
INDEX
xmalloc() uses malloc()
SYNOPSIS
char * my_memory;
my_memory = xmalloc(42); / * my_memory gets address of 42 chars * /
DESCRIPTION
Use xmalloc() as an "error-free" malloc(). It does almost the same job.
When it cannot honour your request for memory it BOMBS your program
with a "virtual memory exceeded" message. Malloc() returns NULL and
does not bomb your program.
