I don't know if it would be useful, but proposing a new interface of the 
form:

	reallocp(&ptr, size)

... to separate the status return from the pointer might be a really 
good idea.  This would hopefully eliminate users doing the "obvious":

	ptr = realloc(ptr, size)

Not that this resolves anything in the short or even medium term, but 
perhaps can help avoid problems in the more distant time frame.  It is 
also an interface which is mostly trivial to infill.
