    IIUC, only when the SIZE argument is 0.  I think many programmers have
    never cared about the NULL-check of the return value of xmalloc where
    they are sure that its argument is positive.  Also we could make
    xmalloc to return a non-NULL value for the case SIZE==0.

Maybe we should make xmalloc give an error when the size is 0.
