Speaking generally rather than specifically about this code, your extra 
checks are redundant when the code is run from a single thread, and 
insufficient if it is later used from multiple threads (accessing the 
same data).  But extra checks can fool people into thinking it is safe - 
since the checks are unnecessary for sequential code they must have been 
put there to catch rare race conditions.


There are times when you want seat-belts /and/ airbags.  But focusing on 
that instead of making sure the driver is competent is not helpful!
