this.numReaders -= 1; //this thread had a read lock
this.numReaders += (2 << 30) //atomic - allow readers to continue
That's a prime example of a very small bug. Compile the code and see how many atoms your atomic code assembles to.

Hello Candy

I did mention earlier that this code is only for working out the logic. I know that you need special assembly code for certain things that why I put the comment "//atomic".

The code will be modified... although I have no idea how to do inline assembly I'll work it out.....
