that might work. i havnt tried it. you need to be carefull
with overflows as 2GB becomes negative with signed 32 bit ints.

	if(dsize >= 0x80000000UL){	/* for sanity, overflow */
		werrstr("invalid allocation size");
		return nil;
	}

the only routine that does substantial allocation is iobufinit()
in cwfs/malloc.c.

as far as i can see, this memory is never freed, so we might
just remove the define:

all.h:13: #define malloc(n)	ialloc(n, 0)

and provide our own ialloc() that just uses brk().
