Kernel.execute(_range, _passes) used much host memory when _passes > 1

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Attached Main.Java used much host memory

What is the expected output? What do you see instead?
LINE 14: kernel.execute(Range.create(512, 64), 2); // <- used huge memory and 
throw OutOfMemoryError
but...
LINE 14: kernel.execute(Range.create(512, 64), 1); // <- not huge
why happened?

What version of the product are you using? On what operating system?
aparapi-2012-05-06, Windows7 SP1 64bit, NVIDIA GeForce GTX 680 as GPU.
(can GTX680 write clinfo?)

Please provide any additional information below.
I think Main class used huge memory only when 
-Dcom.amd.aparapi.executionMode=gpu...
