The Kronecker factor code is *very* slow, and it seems to share
with the Berlekamp factor code a similar bug:
(%i1) e : apply("*", makelist(x + k,k,1,15))$
(%i2) e : expand(e)$
(%i3) factor(e),berlefact : false;
Maxima encountered a Lisp error:
Error in MACSYMA-TOP-LEVEL [or a callee]: Bind stack overflow.
(%i4) factor(e),berlefact : true;
(%o4)
(x+1)*(x+2)*(x+3)*(x+4)*(x+5)*(x+6)*(x+7)*(x+8)*(x+9)*(x+10)*(x+11)*(x+12)*(x+13)*(x+14)*(x+15)
