Previously there was no guarantee that the tests that check for out of memory handling behavior are actually correct - e.g. that they correctly simulate out of memory conditions. Now every simulated out of memory condition has to be "guarded" using CHECK_ALLOC_FAIL. It makes sure that every piece of code that is supposed to cause out-of-memory does so, and that no other code runs out of memory unnoticed.
