I don't think that what you are saying is correct. If you ask the method to allocate a negative number of bytes and the method returns a buffer which is greater than zero, that doesn't seem like a backdoor in the allocation method! Saying you can get a return buffer that is smaller than whatever amount of bytes you requested is wrong I think. Can you give an input to the second method that will result in a buffer smaller than the input value?
