[sage-support] Memory Leak in mutipolynomial evaluation

There is a memory leak in the evaluation of multivariable polynomials: -C.=GF(2)[] -f=x^4+x*y^3+z^6 -get_memory_usage() .1014.47265625 - for i in xrange(100): a=f(1,0,0) -get_memory_usage() .1052.47265625 I think the problem is in the implementation of the __call__ method in rin
