Log:
[USER32_APITEST] -Add a monster of a test to check if WM_DESTROYCLIPBOARD is blocking or
not. Use a critical section while recording as we use a single message cache in two
threads. After 50154, 50816, 50846 and 75616 changing back and forth, this test shows that
75616 is correct and making sure that it won't be changed again in the future,
somehting that would break the ole clipboard.
