Made some improvements, now it's *only* 2x slower than CPython:

~/p/pypy $ ./pypy-c  -mtimeit -s "from array import array; x = array('B', '*' * 
100000)" "x.tostring()"
100000 loops, best of 3: 8.5 usec per loop
~/p/pypy $ ./pypy-c  -mtimeit -s "from array import array; x = array('B', '*' * 
100000)" "x.tostring()"                 🕕 3.62s
100000 loops, best of 3: 8.53 usec per loop
~/p/pypy $ ./pypy-c  -mtimeit -s "from array import array; x = array('B', '*' * 
100000)" "x.tostring()"                 🕐 3.57s
