1997-04-13 17:18  Wolfram Gloger  <wmglo@dent.med.uni-muenchen.de>

	* malloc/malloc.c (fREe): Small optimization.  Before returning,
	add fast check whether the heap containing top can go away.

1997-04-11 16:46  Wolfram Gloger  <wmglo@dent.med.uni-muenchen.de>

	* malloc/malloc.c (mALLOc, rEALLOc, cALLOc, mEMALIGn): When
	failing to allocate a new chunk, also try the main_arena.  It may
	be that we are only running out of mmapped regions, and other
	arenas cannot be enlarged sufficiently.
	(new_heap, malloc_extend_top): Handle top_pad more consistently,
	i.e. only in new_heap().
