The GC_NOTIFY flag is not available in ruby 1.8, it's in 1.9 only. If
you have to use ruby 1.8, you can do it yourself by adding printf
calls at the begining an end of the rb_gc_start function in gc.c.
Under 1.9 the function where GC start is called gc_collect, or at
least that's where GC_NOTIFY is placed.
