2011-04-04	fix rare but nasty under-allocation bug in malloc with large requests	Rich Felker	-1/+1
	the bug appeared only with requests roughly 2sizeof(size_t) to 4sizeof(size_t) bytes smaller than a multiple of the page size, and only for requests large enough to be serviced by mmap instead of the normal heap. it was only ever observed on 64-bit machines but presumably could also affect 32-bit (albeit with a smaller window of opportunity).
2011-04-01	avoid over-allocation of brk on first malloc	Rich Felker	-4/+4
	if init_malloc returns positive (successful first init), malloc will retry getting a chunk from the free bins rather than expanding the heap again. also pass init_malloc a hint for the size of the initial allocation.
2011-03-23	very cheap double-free checks in malloc	Rich Felker	-0/+4

2011-02-20	make malloc(0) return unique pointers rather than NULL	Rich Felker	-5/+9
	this change is made with some reluctance, but i think it's for the best. correct programs must handle either behavior, so there is little advantage to having malloc(0) return NULL. and i managed to actually make the malloc code slightly smaller with this change.
