for those following along at home, the panic is here

	if(c->flag&CFREE)
		panic("cclose %#p", getcallerpc(&c));

and called from

acid; src(0xfffffffff01c45f8)
/sys/src/nix/port/chan.c:240
 235			return;
 236		decref(&npath);
 237		free(p->s);
 238		for(i=0; i<p->mlen; i++)
 239			if(p->mtpt[i])
>240				cclose(p->mtpt[i]);
 241		free(p->mtpt);
 242		free(p);
 243	}
 244
 245	/*

it would be interesting to know if a second try at installation
also fails in the same way.  if it does not, then it will look a lot
like a race in chan.c.  if it fails in the same way, we really can't
infer anything.
