Platform._get_cl_version
test_platform_get_devices
test user event
test_get_host_array
disable get_host_array for MemoryObject without USE_HOST_PTR since the returned array may not be valid
more test for MemoryObject.get_host_array
typo ... I meant ALLOC_HOST_PTR....
only catch expected error in get_host_array() (and not buffer creation)
Merge branch 'pull.test-get_host_array' of github.com:yuyichao/pyopencl into test-get_host_array
