	ah...that's might be all the hint that i needed:

	how about this code in machdep.c 1.199 1996/08/19 line 365

        /* 
         * Finally, allocate mbuf pool.  Since mclrefcnt is an off-size
         * we use the more space efficient malloc in place of kmem_alloc.
         */
        mclrefcnt = (char *)malloc(nmbclusters+PAGE_SIZE/MCLBYTES,
                                   M_MBUF, M_NOWAIT);
        bzero(mclrefcnt, nmbclusters+PAGE_SIZE/MCLBYTES);


	looking at /sys/sys/malloc.h, i dont see what else this might
	be classified as ;(
