-NOTES
-
-       This function uses xmalloc() which is expected to be a front end
-       function to malloc() that deals with low memory situations.  In
-       typical use, if malloc() returns NULL then xmalloc() diverts to an
-       error handler routine which never returns, and thus xmalloc will
-       never return a NULL pointer.  If the client application wishes to
-       deal with low memory situations itself, it should supply an xmalloc
-       that just directly invokes malloc and blindly returns whatever
-       malloc returns.
