Oops :x I added rb_mark_set to the Data_Wrap_Struct calls

benchmark results:
minimum results in each 10 measurements.
Execution time (sec)
name a b
loop_whileloop2 0.104 0.104
vm2_case* 0.072 0.062
vm2_case_lit* 0.540 0.539
vm2_case_small* 0.060 0.053
Speedup ratio: compare with the result of `a' (greater is better)
