Memory issue on cauculations of pyopencl.array.Array

[TsXor]

I tried to let __del__ wait for the events, and surprisingly, it worked:

    def __del__(self):
        self.finish()
        self.base_data.release()

all arrays let their refcount(CL) drop to 0 when they are GC-ed!

I propose to add a switch for the constructor of pyopencl.array.Array. For example, pygc. When it is True, __del__ will work, or __del__ will immediately return.

I think we should add it because manually freeing memory can sometimes be ugly.
For example, manual freeing of mem for

x = somewhatarray
y = x
for _i in range(100):
    y = y*2

should be:

x = somewhatarray
y = x
for _i in range(100):
    y_bak = y
    y = y_bak*2
    y_bak.finish()
    y_bak.base_data.release()
    del y_bak

As far as I can tell, this is all behaving as designed. Please point if that is not so, in your view.
